[ARM] pxamci: add simple gpio controls
The MMC block needs 3 external datas to work : - is the MMC card put in "read-only mode" ? - is a MMC card inserted or removed ? - enable power towards the MMC card Several platforms provide these controls through gpios. Expand the platform_data to request and use these gpios is set up by board code.
