MIPS: qi_lb60: Move MMC configuration to devicetree
Move the MMC configuration from the board C file to devicetree. The 'power' GPIO was removed and instead the vmmc regulator is used, to follow the changes introduced in the jz4740-mmc driver. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Paul Burton <paul.burton@mips.com>
