cmd: Remove mmc_spi command
The mmc_spi command was added to manually setup MMC over SPI bus using command. This was required by the legacy non-DM MMC_SPI driver. With DM based MMC_SPI driver in-place, we can now use all general storge commands and mmc command for MMC over SPI bus hence we remove the mmc_spi command all it's references.

Provides a way to set up an MMC (Multimedia Card) SPI (Serial
|
|
||||||
Peripheral Interface) device. The device provides a means of
|
|
||||||
accessing an MMC device via SPI using a single data line, limited
|
|
||||||
to 20MHz. It is useful since it reduces the amount of protocol code
|
|
||||||
required.
