[v2,3/6] ARM: shmobile: add SDHI and MMCIF interfaces to armadillo800eva-reference

Commit Message

Guennadi Liakhovetski June 6, 2013, 3:48 p.m. UTC

Add SDHI0, SDHI1 and MMCIF interfaces to armadillo800eva-reference. With
no pinctrl DT support we cannot use GPIO card-detection and regulator
switching.
