[PATCH RFC 1/7] ARM: bcm283x: Define pinmuxing for pl011 on board level

[Stefan Wahren]

Until RPI 3 and Zero W the pl011 was always on pin 14/15. So in
order to take care of them and other boards in the future,
we need to define pl011 pinmuxing on board level.

This work based on Eric's patch "ARM: bcm2385: Don't force pl011
onto pins 14/15."
