Jayachandran C. 452f22c389 Merge XLP 3XX updates and related rework.
* Update message station (CMS) code, read queue ids from PCI header.
* Use interrupts to wakeup message handling threads on 3XX
* Update PIC code, read interrupt information from PCI header instead
  of using fixed values.
* Update PCI interrupt handling for the PIC change.
* Update code for getting chip frequency, new code support XLP 3XX
* Misc style(9) fixes

In collaboration with: prabhath at netlogicmicro com (CMS/PIC)
