Enhanced MMC/SD over SPI driver

Original MMC/SD driver supports only Standard Capacity SD cards, besides MMC.
SDSC is becoming increasingly hard to find on the market, while SDHC are
largely available. This bug introduces support for SDHC cards. No attempt was
made to support newer MMC cards. It's been tested with these cards:
MMC Standard 16MB
MMC Standard 32MB
SD Standard Capacity 512MB
SD Standard Capacity 2GB
SD High Capacity 8GB

All cards were tested on both ST32 and Kinetis K60 platforms. SD cards were
tested on Kinetis K70 platform too.

I had no SD Extended Capacity at hand, but, according to SD Physical Layer
Simplified Specification Ver_3.01, it should work also with SDEC cards.
