Daniel Laird edb6310aaa MIPS: Add support for NXP PNX833x (STB222/5) into linux kernel
The following patch add support for the NXP PNX833x SOC.  More
specifically it adds support for the STB222/5 variant. It fixes
the vectored interrupt issue.

* numbers 49..64 for (virtual) GPIO interrupts.
*
* In PNX8335, we have 57 interrupt lines, numbered from 1 to 57,
* connected to PIC, which uses core hardware interrupt 2, and also
* a timer interrupt through hardware interrupt 5.
