mmc: davinci_mmc: Cleanup to use dt in U-boot and static platdata in SPL
Cleanup this driver to use dt in U-boot and static platdata in SPL.
This requires the following steps:
1. Move all platdata assignment from probe() to ofdata_to_platdata().
This function is only called in U-boot.
2. Replicate all the platdata assignment being done in
ofdata_to_platdata() in the omapl138 board file. This data is used in
the SPL case where SPL_OF_CONTROL is not enabled.
3. Remove SPL_OF_CONTROL and related configs from omapl138_lcdk_defconfig
This cleanup effectively reverts 3ef94715cc
