Fixed the prom_relocate() function in start.S file by reserving memory in
the board_init_f sequence and saving the offset to the __prom_start_reloc
variable. This value is used as the destination when relocating the PROM.
Add the prom_init() function to the end of the board_init_r sequence.

Update the LEON2/3 serial driver to make use of the readl and writel
macros as well as the WATCHDOG_RESET() macro.
Add readl/writel and friends to the asm/io.h file.
Introduce the gd->arch.uart variable to store register address.
Lastly, remove baudrate scaler macro variables from board config. It
is now calculated in the serial driver using the global data variable.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.
