* add nested interrupt support for interrupts
+ use a varibale exc_nest_count to trace nest interrupt and exception
+ regular interrupts can be nested by regular interrupts and fast
interrupts
+ fast interrupt's priority is the highest, cannot be nested
* remove the firq stack and exception stack
+ remove the coressponding kconfig option
+ all interrupts (normal and fast) and exceptions will be handled
in the same stack (_interrupt stack)
+ the pros are, smaller memory footprint (no firq stack), simpler
stack management, simpler codes, etc.. The cons are, possible
10-15 instructions overhead for the case where fast irq nests
regular irq
* add the case of ARC in test/kernel/gen_isr_table
