cmd: Remove mmc_spi command

Browse Source 
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.

config CMD_MMC_SPI
bool "mmc_spi - Set up MMC SPI device"
help
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.
