[MAJOR] The SDCard RPI driver first commit

The new driver for RPI added. There are two variants mmc and emmc
for each platform. It's not good solution, because each two implementations
differ by the registers set, the base address and some functionality.
This driver doesn't work. It'll be fixed in the future.
