[PATCH v3 07/14] ARM: shmobile: ag5evm: Remove SDHI .set_pwr() callback

[Laurent Pinchart]

The SHDI platform data .set_pwr() callback is used to control the
vmmc/vqmmc power supplies. As the power supplies already register
control GPIOs there's no need to perform the operation manually.
Remove the callback functions.
