[ARM] 4966/1: magician: add MFP pin configuration 



Although the GPIO alternate functions should be correctly set
by the bootloader, configure them here to be sure.
To save power, FFUART/BTUART/STUART are left unconfigured (output, low)
until they are needed by pxaficp or the magician GSM chipset driver.
