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.
Unlike the previous revision of this patch:
https://lore.kernel.org/lkml/20200625001039.56174-5-john.stultz@linaro.org/
this version reworks PINCTRL_MSM to be a visible option and
instead of having the various SoC specific drivers select
PINCTRL_MSM, this switches those configs to depend on
PINCTRL_MSM. This avoids adding the oddish looking:
"depend on QCOM_SCM || QCOM_SCM=n"
to every SoC specific driver, as that becomes a maintenance
headache.

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.
v3:
* Make sure the QCOM_SCM || QCOM_SCM=n trick is commented
v4:
* Rework "select PINCTRL_MSM" to "depends on PINCTRL_MSM"
to consolidate the QCOM_SCM dependency.

Allow the qcom_scm driver to be loadable as a permenent module.
This still uses the "depends on QCOM_SCM || !QCOM_SCM" bit to
ensure that drivers that call into the qcom_scm driver are
also built as modules. While not ideal in some cases its the
only safe way I can find to avoid build errors without having
those drivers select QCOM_SCM and have to force it on (as
QCOM_SCM=n can be valid for those drivers).

Doh. Apologies! I flubbed this line (SCM not QCM). I'll fix and
resend tomorrow.
