RCar-H2: boot from SD card request

[Ben Dooks <ben.dooks@codethink.co.uk>]

I am trying to boot an lager board from SD, using SDHI0 channel with
the development branches from Simon.

Has anyone got this to work? I have a working 3.4-ltsi kernel that
can boot

I've tried the next, master and devel branches from
  git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git

My current diffs to the source are:
