mx53loco: Fix revision of Dialog boards
Original code was assuming that the fuse revision version for all mx53loco boards
based on Dialog PMIC was the same, which is not the case.
Force the revision of all Dialog-based boards to 0.
This fixes a kernel crash when PMIC is accessed in the 2.6.35 kernel
for Dialog rev E boards.
