[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.
