This adds support for the sdmmc and emmc ports on the rk3288 using the currently posted driver from Addy at: https://patchwork.kernel.org/patch/4520631/ This enables basic SD and eMMC support. Things are not yet running at the fastest speed and we don't have the regulators specified, but we can at least use the eMMC and SD cards now. A few notes: * Doesn't enable DDR mode from eMMC since it didn't work on Addy's patch. A future patch enables it. * This is not baesd on Jaehoon's patch series removing the slot node, but it does use new syntax like putting the bus width at the top level and using the new cap-mmc-highspeed / cap-sd-highspeed. A future patch will modify this one to remove the slot node.
