mmc: update Faraday FTSDC010 for rw performance
Faraday FTSDC010 is a MMC/SD host controller.
Although there is already a driver in current u-boot release,
which is modified from eSHDC and contributed by Andes Tech.
Its performance is too terrible on Faraday A36x SoC platforms,
so I turn to implement this new version of driver which is
10+ times faster than the old one.
It's carefully designed to be compatible with Andes chips,
so it should be safe to replace it.
