 * The "IRQ numbers" are completely virtual.

 * In PNX8330/1, we have 48 interrupt lines, numbered from 1 to 48.
 * Let's use numbers 1..48 for PIC interrupts, number 0 for timer interrupt,
 * 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.
 * Let's use numbers 1..64 for PIC interrupts, number 0 for timer interrupt,
 * numbers 65..80 for (virtual) GPIO interrupts.
