Subject: [PATCH v2 4/5] pinctrl: qcom: Allow pinctrl-msm code to be loadable as a module
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.
This requires that we tweak Kconfigs selecting PINCTRL_MSM to
also depend on QCOM_SCM || QCOM_SCM=n so that we match the
module setting of QCOM_SCM.

v2:
* Module description and whitespace fixes suggested by Bjorn
* Added QCOM_SCM || QCOM_SCM=n bits on Kconfigs selecting
PINCTRL_MSM. Reported by both Todd and Bjorn.
