ppc4xx: Use common NS16550 driver for PPC4xx UART
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
