mmc: sandbox: rename CONFIG, fix dependency, and use it in Makefile
[1] Rename CONFIG_SANDBOX_MMC to CONFIG_MMC_SANDBOX for consistency
I want all MMC driver options prefixed with CONFIG_MMC_.
[2] Fix dependency
Add necessary depends on to avoid compile error.
Instead "depends on MMC" is unneeded because this config entry
resides inside of "if MMC".
[3] Currently, this config symbol is not referenced at all.
Use it to enable/disable the driver in Makefile.
