Convert low-level debugging routines to make use of debug_ll_io_init().
This is part of the preparation for ARCH_MULTIPLATFORM support for Zynq.

Move Tegra's debug-macro.S over to the common debug macro directory.
Move Tegra's debug UART selection menu into ARM's Kconfig.debug, so that
all related options are selected in the same place.
Tegra's uncompress.h is left in mach-tegra/include/mach; it will be
removed whenever Tegra is converted to multi-platform.

imx6q gets 5 uart ports in total. Different board design may choose
different port as debug uart. For example, imx6q-sabresd uses UART1,
imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4. Rather than
bloating DEBUG_LL choice list with all these uart ports, the patch
introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number
when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.

After "ARM: vexpress: Make the debug UART detection more specific",
building allyesconfig in linux-next now gives me:
arch/arm/kernel/debug.S: Assembler messages:
arch/arm/kernel/debug.S:81: Error: selected processor does not support ARM mode `movw r2,#0xc 091'
arch/arm/kernel/debug.S:81: Error: selected processor does not support ARM mode `movt r2,#0x4 10f'
arch/arm/kernel/debug.S:97: Error: selected processor does not support ARM mode `movw r2,#0xc 091'
arch/arm/kernel/debug.S:97: Error: selected processor does not support ARM mode `movt r2,#0x4 10f'

arch/arm/kernel/debug.S:104: Error: selected processor does not support ARM mode `movt r3,#0x 410f'
Since the code can never get executed on ARMv6 but might
be built in a configuration that has ARMv6 enabled, it's
safe to just mark it in the assembly source for being
ARMv7-only.

This fixes early_printk() compilation for
socfpga. (senduart/busyuart/waituart were missing). It does that by
making Picochip code generic.

Base the UART detection heuristic on architecturally defined
MIDR register instead of implementation dependent CBAR. The
only tile using the original memory map is V2P-CA9 with Cortex
A9 r0p1, which MIDR contains value 0x410fc091.

Move imx debug-macro.S over to common debug macro directory. It
removes the inclusion to hardware.h by hard-coding the physical
address of uart port and copying IMX_IO_P2V from hardware.h.
Since we will need a common solution, which might use a fixed virtual
address for uart port across platforms, we make a copy of IMX_IO_P2V
here as a temporary solution to enable low-level debug for imx
multi-platform build.
