asm-generic: build fixes for v5.15

There is one build fix for Arm platforms that ended up impacting most
architectures because of the way the drivers/firmware Kconfig file is
wired up:

The CONFIG_QCOM_SCM dependency have caused a number of randconfig
regressions over time, and some still remain in v5.15-rc4. The
fix we agreed on in the end is to make this symbol selected by any
driver using it, and then building it even for non-Arm platforms with
CONFIG_COMPILE_TEST.

To make this work on all architectures, the drivers/firmware/Kconfig
file needs to be included for all architectures to make the symbol
itself visible.

In a separate discussion, we found that a sound driver patch that is
pending for v5.16 needs the same change to include this Kconfig file,
so the easiest solution seems to have my Kconfig rework included in v5.15.

There is a small merge conflict against an earlier partial fix for the
QCOM_SCM dependency problems.

Finally, the branch also includes a small unrelated build fix for NOMMU
architectures.
