Tweaks to allow pinctrl-msm code to be loadable as a module.
This is needed in order to support having the qcom-scm driver,
which pinctrl-msm calls into, configured as a module.

Unless there are dependencies on the irqchip patches I can apply
this if Bjorn is OK with it.

This means that we need a "depends on QCOM_SCM || QCOM_SCM=n" on all
entries in the Kconfig that selects PINCTRL_MSM, or switch PINCTRL_MSM
to be user selectable and make all the others depend on it.

Oh, good point! I already had to fix that in a different tree, but
forgot to move the fix over to my upstreaming tree.
