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

Add support for dynamical allocation of imx-keypad on mx5 platform.
After moving to dynamically registration of the keypad, the keypad clock
name needs to change accordingly.
The reason is that the original mx5 keypad platform_device id was 0,
now we use id=-1 as per arch/arm/plat-mxc/devices/platform-imx-keypad.c.
Tested keypad successfully on a MX51_3DS board.

Current code doesn't really enable the usb clocks so if they're disabled
when booting linux, the kernel/machine will hang as soon as someone is trying
to read a usb register

Instead of reading the silicon version from ROM, we should
read the SREV register from the IIM.
Freescale has dropped all support for MX51 REV1.0, only MX51
REV 2.0 and 3.0 are valid.
