base-files: add minimal mmc support
Added minimal mmc support for helper functions:
- find_mmc_part: Look for a given partition name. Returns the
coresponding partition path
- caldata_extract_mmc: Look for a given partition name and then
extracts the calibration data
- mmc_get_mac_binary: Returns the mac address from a given partition
name and offset

[replace dd with caldata_dd, moved sysupgrade mmc to orbi]
