Make of_device_id array const, because all OF functions handle it as const.

In case of error, the function devm_ioremap_nocache() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Add driver for HDMI output.
HDMI PHY registers are mixed into HDMI device registers
and their is only one IRQ for all this hardware block.
That is why PHYs aren't using phy framework but only a
thin hdmi_phy_ops structure with start and stop functions.
HDMI driver is mapped on drm_bridge and drm_connector structures.
