pp bootloader: speed up loading of the OF in the mi4 format
This change replaces an odd way to increment tea key in a function responsible
for finding the proper key (it doesn't have to be done in a for loop, it's just
adding a 32bit number to a 128bit number). It reduces the time needed to find
the key practically to zero and it gives in the best case 2 seconds of overall
speedup in loading the OF.
