soc/amd/*/uart: commonize UART code and MMIO device driver

Now that the SoC-specific UART controller data and the common code part
are cleanly separated, move the code to the common AMD UART support
block folder. The code is identical to the UART code in Cezanne,
Mendocino, Morgana and Picasso while Stoneyridge doesn't use the parts
related to the MMIO device driver.
