This patch removes the PPC4xx UART driver. Instead the common NS16550
driver is used, since all PPC4xx SoC's use this peripheral device.
The file 4xx_uart.c now only implements the UART clock calculation
function which also sets the SoC internal UART divisors.
All PPC4xx board config headers are changed to use this common NS16550
driver now.
Tested on these boards:
acadia, canyonlands, katmai, kilauea, sequoia, zeus

This patch adds new macros, with frequently used combinations of the
4xx TLB access control and storage attibutes. Additionally the 4xx init.S
files are updated to make use of these new macros. Resulting in easier
to read TLB definitions.
Additionally some init.S files are updated to use the mmu header for the
TLB defines, instead of defining their own macros.
