[RFC PATCH 0/7] UHS-I support for sh_mobile_sdhi

This series adds support for UHS-I in sh_mobile_sdhi, partly implemented
in tmio_mmc. This does not yet include tuning for SDR-104, but SDR-50
works.

The pfc block needs to be configured for 1.8V or 3.3V signalling on the
SDHI, separately from the external voltage regulator. I've treated this
as an additional regulator that sh_mobile_sdhi has to adjust, but I'm
not entirely happy with this or the way it's represented in the DT. I
would appreciate advice on how to improve that.

Ben.
