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.

We also add PINCTRL_MSM to the arm64 defconfig to avoid
surprises as otherwise PINCTRL_MSM/IPQ* options previously
enabled, will be off.

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.
v5:
* Add PINCTRL_MSM to arm64 defconfig

Bjorn can you have a look at this series?

BTW John  I'm afraid I just merged a new QCOM subdriver so we might
need to respin this to cover all.

It's an important patch so I'll help out in rebasing it if the only problem is
that my tree is moving under your feet.

Yours,

No worries. I'm mostly wanting to make sure there are no objections
with switching PINCTRL_MSM from a selected config to a depended
config.

If that seems ok, I can redo it on whatever point you would like.

I realize I can also split that change out separately from the module
enablement bits as well if its helpful.

thanks
