This function is essentially independent from tffp, and will also be
utilised in implementing UEFI capsule update in a later commit.
So just give it a more generic name.
In addition, a new configuration option, CONFIG_DFU_ALT, was introduced
so that the file will be compiled with different options, particularly
one added in a later commit.
