[PATCH V6 01/20] include: env: ti: mmc: envboot/mmcboot: Check result of mmc dev before proceeding

[Nishanth Menon]

If mmc dev reports that the device is not present, there is no point in
proceeding further to attempt to load the files.

new patch -  noticed a series of 'MMC: no card present' in boot log
and was wondering why, now I know - shaves off 2 seconds or so into boot
process.
