[PATCH] m68knommu: new family (523x) and board config support

New architecture and board configuration support for m68knommu.

. add 523x ColdFire support
. add support for SOM5282 and MOD5272 boards
. break up the 527x to be separate 5271 and 5275. There is some
  subtle differences that (like RAM config) that need to be dealt with
. add option to support selecting 4k kernel stack
