configs: omap5: Enable custom mmc boot to distroboot for AM57x

Browse Source 
TI AM57x boards use a custom (though family common to TI boards) mechanism
for booting Linux. Add support to enable custom MMC boot as a default
option along with the distroboot approach.

Also, add supporting mmc boot environment variables which shall be used for
custom MMC boot
