[PATCH 1/2] irqchip/qcom-pdc: Switch to IRQCHIP_PLATFORM_DRIVER and allow as a module

[John Stultz]

From: Saravana Kannan <saravanak@google.com>

This patch revives changes from Saravana Kannan to switch the
qcom-pdc driver to use IRQCHIP_PLATFORM_DRIVER helper macros,
and allows qcom-pdc driver to be loaded as a permanent module.

Earlier attempts at this ran into trouble with loading
dependencies, but with Saravana's fw_devlink=on set by default
now we should avoid those.

[PATCH 2/2] firmware: QCOM_SCM: Allow qcom_scm driver to be loadable as a permenent module

[John Stultz]

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).

Reviving this now that Saravana's fw_devlink defaults to on,
which should avoid loading troubles seen before.
