With QCA4019 platform, SRAM address can be accessed directly from host but
currently, we are assuming sram addresses cannot be accessed directly and
hence we convert the addresses.
While there, clean up growing hw checks during conversion of target CPU
address to CE address. Now we have function pointer pertaining to different
chips.

Rx filter reset and the dynamic tx switch mode (EXT_RESOURCE_CFG)
configuration are causing the following errors when UTF firmware

The problem is due to rtl8192ce and rtl8192cu sharing routines, and having
different layouts of struct rtl_pci_priv, which is used by rtl8192ce, and
struct rtl_usb_priv, which is used by rtl8192cu. The problem was resolved
by placing the struct bt_coexist_info at the head of each of those private
areas.

This patch fixes the issue specific to AP. AP is started with WEP
security and external station is connected to it. Data path works
in this case. Now if AP is restarted with WPA/WPA2 security,
station is able to connect but ping fails.
Driver skips the deletion of WEP keys if interface type is AP.
Removing that redundant check resolves the issue.

When resuming, it's possible for the following scenario to occur:
* iwl_pci_resume() enables the RF-kill interrupt
* iwl_pci_resume() reads the RF-kill state (e.g. to 'radio enabled')
* RF_KILL interrupt triggers, and iwl_pcie_irq_handler() reads the
state, now 'radio disabled', and acquires the &trans_pcie->mutex.
* iwl_pcie_irq_handler() further calls iwl_trans_pcie_rf_kill() to
indicate to the higher layers that the radio is now disabled (and
stops the device while at it)
* iwl_pcie_irq_handler() drops the mutex
* iwl_pci_resume() continues, acquires the mutex and calls the higher
layers to indicate that the radio is enabled.
At this point, the device is stopped but the higher layers think it's
available, and can call deeply into the driver to try to enable it.
However, this will fail since the device is actually disabled.

In DQA mode the check whether to decrement the pending frames
counter relies on the tid status and not on the txq id.
This may result in an inconsistent state of the pending frames
counter in case frame is queued on a non aggregation queue but
with this TID, and will be followed by a failure to remove the
station and later on SYSASSERT 0x3421 when trying to remove the
MAC.
Such frames are for example bar and qos NDPs.
Fix it by aligning the condition of incrementing the counter
with the condition of decrementing it - rely on TID state for
DQA mode.
Also, avoid internal error like this affecting station removal
for DQA mode - since we can know for sure it is an internal
error.

A few of the static queues are enabled along with the bcast
STA. Make sure they are removed along with it, rather than
waiting for the mac ctxt release.
This is needed because we sometimes have a STA being removed
and then added again (either with the same sta_id or a
different one). If we wait for the mac ctxt release we will
try to allocate the queues again (as this is currently done
in the STA allocation and not in the MAC init) although
they weren't freed, and even if the sta_id of the STA has
changed.

Instead of setting the tx_cmd length in the mvm code, which is
complicated by the fact that DQA may want to temporarily store
the SKB on the side, adjust the length in the PCIe code which
also knows about this since it's responsible for duplicating
all those headers that are account for in this code.
As the PCIe code already relies on the tx_cmd->len field, this
doesn't really introduce any new dependencies.
To make this possible we need to move the memcpy() of the TX
command until after it was updated.
This does even simplify the code though, since the PCIe code
already does a lot of manipulations to build A-MSDUs correctly
and changing the length becomes a simple operation to see how
much was added/removed, rather than predicting it.

We don't really need clear the skb's status area nor store the
dev_cmd into it until we really commit to the frame by handing
it to the transport - defer those operations until just before
we do that.
This doesn't entirely fix the bug with frames not getting sent
out after having been deferred due to DQA, because it doesn't
restore the info->driver_data[0] place that was already set to
zero (or another value) by the A-MSDU logic.

The firmware will soon actually look at the AID field, and
when it does that it'll try to ensure that the AID is never
changing. Due to the way the station is added, it may start
with an invalid AID before it's associated, so to ensure a
constant AID (once it becomes non-zero), track the station
state and set the AID only when the station is associated
and when it disassociates.

When driver needs to access the contents of a streaming DMA buffer
without unmapping it it should call dma_sync_single_for_cpu().
Once the call has been made, the CPU "owns" the DMA buffer and can
work with it as needed.
Before the device accesses the buffer, however, ownership should be
transferred back to it with dma_sync_single_for_device().
Both calls weren't performed by the driver, resulting with odd paging
errors on some platforms. Fix it.
