IO Expander: add the interrupt support to IOEX framework
This CL creates interfaces which bring the IOEX framework to support
interrupt feature.
To declare an IOEX IO which supports the interrupt function, file its
declaration in gpio.inc with the format:
IOEX_INT(name, expin, flags, signal)
Note: like GPIO, all IOEX IOs with interrupt handlers must be declared
at the top of the IOEX's declaration in the gpio.inc
The following two APIs are added to enable/disable each IOEX IO's
interrupt function:
1. ioex_enable_interrupt
2. ioex_disable_interrupt
BRANCH=none
BUG=none
TEST=No error for "make buildall"
TEST=Apply this and related CLs, manually test each IO pins; make sure
each pin's interrupt handler is correctly executed.
