Adrien Destugues 522c141d53 [WIP] sd/mmc: enable high speed transfers
- Switch to 25MHz clock
- Switch to 4bit transfers mode (the default is 1bit)

Reading and writing SD cards do not seem to work anymore with these
changes. I get invalid data on read, and on write, an interrupt is never
called in some cases.
