ARM: mx51: Print silicon revision on boot
Having the silicon revision to appear on the boot log is a useful information.
MX31 and MX35 already show the silicon revision on boot.
Add support for displaying such information for MX51 as well.
Tested on a MX51EVK, where it shows:
CPU identified as i.MX51, silicon rev 3.0
