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. Signed-off-by: Francois Retief <fgretief@spaceteq.co.za>
