[PARISC] Use kzalloc and other janitor-style cleanups

Helge,
  o Convert a bunch of kmalloc/memset uses to kzalloc.
  o pci.c: Add some __read_mostly annotations.
  o pci.c: Move constant pci_post_reset_delay to asm/pci.h
  o grfioctl.h: Add A4450A to comment of CRT_ID_VISUALIZE_EG.
  o Add some consts to perf.c/perf_images.h

Matthew,
  o sticore.c: Add some consts to suppress compile warnings.
