[PATCH v2 05/11] mci: atmel_mci: Add PBL helper to configure highcapacity

[Sam Ravnborg <sam@ravnborg.org>]

Older atmel SoC's like at91sam9263 do not support highcapacity SD cards.
Add helper that can be used to disable highcapacity support
in the PBL code - as probing for the SD card type is not an option.
