[SPARC64]: Fix more of_device layer IRQ bugs, and correct PROMREG_MAX.

Browse Source 
Sabre and Psycho PCI controllers can have partial interrupt-map
properties, meaning that on-board devices don't match up to any
entries.  Instead, they are fully specified from the beginning and
we should pass them directly to the IRQ translator as-is.

Also, fill in the necessary translator slots for the "graphics"
and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS.

Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices.

Finally, prevent accidentally writing past the end of the of_device
struct resource[] and irqs[] arrays.  Spit out a log message when
we ignore some entries because there are too many of them.
