ARM: mx53: Print silicon revision on boot
Having the silicon revision to appear on the boot log is a useful information.
MX31, MX35 and MX51 already show the silicon revision on boot.
Add support for displaying such information for MX53 as well.
Tested on a mx53loco board, where it shows:
CPU identified as i.MX53, silicon rev 2.0
