[PATCH v3 8/8] ARM: shmobile: completely switch MMC interfaces on armadillo800eva-reference to DT

[Guennadi Liakhovetski]

Switch MMCIF, SDHI0 and SDHI1 to complete DT initialisation: use DT
bindings to configure regulators, interface pins, card-detect GPIOs,
various interface configuration parameters.
