This patch enhances the generic SD-card protocol implementation in
sd-card.h with the ability to handle the version 1.0 of the CSD register
(containing the capacity information of older SD cards).
The driver for the Freescale eSDHCv2 doesn't support the highest
available bus frequency by now and also the bus width may be set to a
higher value but that needs further checks on the capabilities of the
inserted card.
The commits provide a benchmark as it exists for the OMAP4 SDHC driver.
