Joseph Chen 4e6670fe63 drivers: add irq interrupt framework support 
This patch add support for IRQ interrupt, FIQ not included.
It will be enabled when you select CONFIG_GICV2 or CONFIG_GICV3.

The framework support gic interrupt and gpio interrupt, relative APIs
are provided in: ./include/irq-platform.h

If you'd like to add a new platform support into interrupt framework,
please follow the steps:
1. add relative definitions in the file like other platforms:
   	./include/irq-platform.h

2. add GICD, GICC and GICR(for GICV3) base address definitions in the
   rkxxx-common.h, they are needed in: arch/arm/cpu/armv8/start.S;

3. enable CONFIG_GICV2 or CONFIG_GICV3.

Notice:
1. the framework is initialize in function 'interrupt_init()' of
   _sequence_r[]. So you should not request irqs too early.

2. IRQ stack size is configured by CONFIG_IRQ_STACK_SIZE, the default
   value is 8KB when CONFIG_IRQ_STACK_SIZE is absent.
