Merge support for Gateworks Cambria boards:

o add support for IXP435 cpu's (e.g. 64 irq's)
o add support for Cambria-specific devices: npe, led's (front panel and
  octal latch), ehci, mcu, ide cf
o redo memory mapping for xscale/ixp4xx boards: previously memory
  was assumed aliased to 0x10000000 but this appears to be true only
  for ixp425 systems and breaks operation on others; rework so memory
  is assumed to start at 0
o rework NPE configuration support to use NPE id's instead of port #'s;
  these changes also rename the associated MAC's to follow the NPE's
  they are attached to
o update npe firmware to latest rev (same license) and update default fw
  imageid's to match; in particular this adds NPE-A and crypto support
o re-style NPE fw handling code and add a console msg identifying the
  attributes of the loaded fw
o fix numerous problems with handling failures during npe setup
o fix npe rx q setup; need to spin waiting for mailbox responses during
  early boot stages as qmgr interrupts are not delivered; this fixes
  the problem where all 8 traffic classifications were not tied to the
  rx q (and eliminates the console msg "remember to fix rx q setup")
o add DELAY to npe MII wait logic for IXP435
o strip down builtin phys->virt address translation table in resource
  handling to just those resources that require it and add a console msg
  to alert people when this (kludge) table needs to be extended
o purge a bunch of dead netbsd-ism's
o cleanup avila led driver
o add Cambria support to boot2 and rework code for better multi-board support

Notes:
  1. NPE-A doesn't work and causes NPE-C to stop working; it is disabled
     in the hints
  2. USB isn't working yet; controller communicates ok but device
     discovery fails
  3. Cambria support must be configured separately from IXP425 boards;
     multi-board support is TBD
