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
