arm: mvebu: Espressobin: Disable slot when emmc is not present
This change extends previous commit 061c6d1b238a ("arm: mvebu: Espressobin:
Detect presence of emmc at runtime") and when emmc is not present then emmc
is removed from U-Boot DM and corresponding slot is disabled. Therefore on
Espressobin board without soldered emmc, state of emmc hw should be same as
if emmc was disabled in DTS.
