[PATCH][PPC32] Marvell host bridge support (mv64x60)

This patch adds core support for a line of host bridges from Marvell (formerly Galileo).  This code has been tested with a GT64260a, GT64260b, MV64360, and MV64460.  Patches for platforms that use these bridges will be sent separately.

The patch is rather large so a link is provided.
