c79504e73a mx5: change usb clock source from pll3 to pll2
For power management reasons, pll2 should be used to source the USBOH3
clock for mx51. PLL3 can be completely gated off when USB is not used.

This patch applies to 2.6.34-rc7.

fc300206ad i.MX51: remove NFC AXI static mapping
This area contains the Nand Flash controller registers. There
is no need to map them statically as the Nand driver uses ioremap().

5443856cad i.MX51: determine silicon revision dynamically
Freescale redboot passes the silicon revision via
ATAG_REVISION. Remove this bootloader dependency by
doing the same as redboot does in the Kernel.

3d1bc8626c i.MX51: map TZIC dynamically
This looks cleaner and allows us to call mx51_revision
later when we can use ioremap to determine the silicon
revision dynamically.
