common/board_f: Catch bloblist before starting reservations

Start reservations needed for init sequence only after catching
bloblists from previous stage.

This is to avoid catching bloblists in the middle causing gaps while
u-boot is reserving.

Adjust the relocaddr as per video hand-off information received from
previous stage so that further reservations start only after regions
reserved for previous stages

Skip reservation for video memory if it was already filled by a
bloblist.
