1) Advertise the actual min / max speeds the hardware is capable
of supporting given the reference clock used by the board.
2) Rather than attempting to extend the hardware's timeout register
in software (the hardware doesn't have sufficient bits to directly
support long timeouts), simply implement the same timeout approach
used in the SDXC driver.
3) Set the timeout for a linked command (e.g. STOP TRANSMISSION) based
on the previous multiblock read / write.
The changes have been smoke tested on both the ODROID-C1 and the VSATV102-M6
using the following cards:
* PQI 2GB microSD
* SanDisk 2GB microSD
* PQI 8GB SDHC (not a microSD so only tested on the ATV-102)
* PNY 8GB microSDHC
* SanDisk Ultra 32GB microSDHC
