ARM: nomadik: selectively enable UART0 on boards
The S8815 board is using RX/TX on UART0, and the NHK8815 is
using RX/TX and CTS/RTS (the latter connected to a Bluetooth
chip). Activate the right groups with the u0 UART0 function
on each board and undisable it. Get rid of the old erroneous
default definition from the SoC file.
