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.

Add support for the new smp_twd runtime registration interface
to the imx6q platforms, and remove the old compile-time support.

The imx6q DTS file is updated to match the TWD DT documentation.
Also present in this patch a DTS fix to the timer interrupt routing
(the PPI connection uses bits [15:8]) and trigger (rising edge).

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.

When gpio core dynamically allocate gpio number for a port, it starts
from the end of the total range, 0 ~ ARCH_NR_GPIOS.  That said, the
earlier a port gets probed, the bigger gpio number it gets assigned.
To match this, the irq_base for gpio should be assigned from
'MXC_GPIO_IRQ_START + ARCH_NR_GPIOS' decreasingly.

The of_irq_init() expects the callback passed by .data of of_device_id
return 'int' instead of 'void'.  This patch fixes it to have
irq_init_cb() return the correct value, and in turn have the secondary
interrupt controller (gpio in this case) initialized properly and also
eliminate the error message 'of_irq_init: children remain, but no
parents' which was overlooked before.
