ARM: dts: Select the PL011 platform driver

The PL011 driver in this downstream kernel tree supports an extra
compatible string - arm,pl011-axi - for use by RP1. This registers as a
platform driver, not an AMBA driver, and has the advantage of responding
to dynamic Device Tree changes such as loading one of the "uart<n>"
overlays.

Change all of the downstream Raspberry Pi dts files to use the new
compatible string. At the same time, remove the override of the periphid
as the upstream code now has the correct value.
