sparc: Update LEON serial drivers to use readl/writel macros
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.
