mmc: host: add Coldfire esdhc support
This driver has been developed as a separate module starting from the similar sdhci-esdhc-imx.c. Reasons for a separate sdchi-esdhc-mcf driver: - m68K architecture does not support devicetrees, so modifying sdhci-of-esdhc.c that is devicetree-related adding platform data seems not appropriate, - clock-related part, has to be implemented specifically for mcf5441x family (see esdhc_mcf_pltfm_set_clock()), - this is a big endian cpu accessing a big endian controller, but about sdma, this controller does not support hw swap, which needs to be handled with specific code, - some other minor differences but mainly to avoid risks on tweaking inside largely used imx driver. Adding just a small size ColdFire-specific driver, with benefits in a further less risky maintenance.
