Start populating mmc/mmc_hl_cmds.c. Create mmc directory in preparation

for making it a library.

mmc.h:  CDIO_MMC_GPCMD_ALLOW_MEDIUM_REMOVAL ->
        CDIO_MMC_GPCMD_PREVENT_ALLOW_MEDIUM_REMOVAL
mmc.c:  Move mm_eject_media and mmc_set_drive_speed to mmc/mmc_hl_cmds.c
mmc_ll_cmds.c: add mmc_prevent_allow_medium_removal,
               move mmc_mode_sense to mmc/mmc_hl_cmds.c
