bcm2835-sdhost: Major revision

Browse Source

This is a significant revision of the bcm2835-sdhost driver. It
improves on the original in a number of ways:

1) Through the use of CMD23 for reads it appears to avoid problems
   reading some sectors on certain high speed cards.
2) Better atomicity to prevent crashes.
3) Higher performance.
4) Activity logging included, for easier diagnosis in the event
   of a problem.
