linux: Update to v4.2.6-openpower1

 - Rebased on upstream stable release v4.2.6
 - Dropped "ast: Default to 8bpp on big endian", as we do not build
   for big endian, and there was no interest in upstreaming this patch
 - Dropped "fbcon: initialize blink interval before calling" as this is
   in the upstream stable release
