ARM: ux500: move UART pin control to the device tree

Browse Source 
This moves the static, device-tied pin control configuration
out of the board file board-mop500-pins.c and into the device
tree.

We create a new .dtsi-file to be shared between all the
MOP500-related boards, that include all HREF variants and
the Snowball board. Assign pin states for HREF and Snowball
boards alike.
