Detect CPU type at runtime and setup uarts accordingly; also clean up the
uart base address mess in the process as far as possible.

This patch replaces the general alchemy prom_putchar() implementation
in favor of board-specific versions: The UART where the output of
prom_putchar is directed to really depends on the board, the current
implementation hardcodes this on a per-SoC basis which is just wrong.
So a generic uart tx function is provided in the alchemy headers,
and the boards can provide their own prom_putchar with custom
destination uart, and all in-kernel alchemy boards support
early printk.

Since memsize is unsigned, it would seem better to use strict_strtoul that
strict_strtol.
A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@s2@
long e;
position p;
@@
strict_strtol@p(...,&e)
@@
position p != s2.p;
type T;
T e;
@@
- strict_strtol@p
+ strict_strtoul
(...,&e)
// </smpl>
