gpio/em: Add Device Tree support

Browse source

Update the Emma Mobile GPIO driver to add DT support.

The patch simply adds a two-cell xlate function and
updates the probe code to allow configuration via DT
using the "ngpios" property plus OF id in the same
style as gpio-mvebu.c. The code is also adjusted to
use postcore_initcall() to force early setup.
