Subject: gpio/mxs: adopt irq_domain support for mxs gpio driver
Remove irq_domain_add_legacy call from mach-mxs.c and have the gpio
driver adopt irqdomain support, so that we can have the mapping
between gpio and irq number available without using virtual_irq_start
and MXS_GPIO_IRQ_START.

Subject: ARM: mxs: retrieve timer irq from device tree
Rather than using the static timer irq definition, we should retrieve
timer irq from device tree for better.
