Hi Yi-Sheng

The v2_drivers provide the list of OKL4 native drivers to build 
for the platform.

This is in the form of ( a, b, c, d ), where a is the actual
driver for the hardware, b is the glue and infrastructure code
common across a class of drivers (e.g. serial, timer, etc), c 
is the address in physical space where the registers for the
hardware device are located, and d specifies the interrupt
numbers for the device.
