mxs: disable unused serial drivers
This disables PL010 and 8250 serial support for this platform as both drivers are not used: the debug UART is PL011 and the application UARTs use a dedicated MXS specific driver. The kernel size reduction is neglectable, but it also removes the non-working (confusing) /dev/ttyS0 and /dev/ttyS1 devices in a running system (which generate errors when trying to use): root@OpenWrt:~# echo "hello world" > /dev/ttyS0 ash: write error: I/O error root@OpenWrt:~# Signed-off-by: Michael Heimpold <mhei@heimpold.de>
