ipq40xx: fix gpio-hog related boot issues

The pinctrl initialization fails with the MSM pinctrl code and gpio-hogs
because either the gpio ranges are not yet initialized (missing gpio-range
in DT) or that the msm driver unconditionally tries to re-initializes the
ranges (gpio-range in DT).

To allow gpio-hogs and similar early-boot gpio code, the gpio-ranges must
be in the device tree and the pinctrl-msm code must check whether the range
was already initialized by the DT.
