MX: serial_mxc: cleanup removing nasty #ifdef

The serial driver for iMX SOCs is continuosly changed if a
new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port>
defines were used only to find the base address for the selected UART.
Instead of that, move the base address to the board configuration
file and drop all #ifdef from driver.
