There is no need for adding board related entries into dt_board_compat.

Leave only the SoC entry.

This way we do not need to patch a C file when adding dt support for
a new board.

Move irq_domain_add_legacy call from imx5*-dt.c into tzic init function
and have the tzic driver adopt irqdomain support for both DT and non-DT
boot.

Now tzic init function calls irq_alloc_descs to get irq_base and adds
a lenacy irqdomain with the irq_base, so that the mapping between tzic
irq and Linux irq number can be handled by irqdomain.

Move irq_domain_add_legacy call from imx*-dt.c into gpio driver and
have the gpio driver adopt irqdomain support for both DT and non-DT
boot.

With all imx platform code converted from static gpio irq number
computation to use run-time gpio_to_irq call, we can now use
irq_alloc_descs and irqdomain support to dynamically get irq_base
and have the mapping between gpio and irq number available without
using virtual_irq_start and MXC_GPIO_IRQ_START.

Apart from the iomux setup which may not be needed on custom
boards the kernel starts fine using the devicetree, so add
generic boards to the dt_compat entries.

irq_domain_add_simple() was a stop-gap measure until complete irq_domain
support was complete.  This patch removes the irq_domain_add_simple()
interface.

This patch also drops the explicit irq_domain initialization performed
by the mach-versatile code because the versatile interrupt controller
already has irq_domain support built into it.  This was a bug that was
hanging around quietly for a while, but with the full irq_domain which
actually verifies that irq_domain ranges are available it would cause
the registration to fail and the system wouldn't boot.

v4: Fixed number of irqs in mx5 gpio code
v2: Updated to pass in host_data pointer on irq_domain allocation.

This patch moves the contents of arch/arm/mach-mx5 to arch/arm/mach-imx
and adjusts the Makefile/Kconfig entries in a way that it's possible
to compile i.MX5 together with i.MX3/6.
