Recently when debugging why one of the scmi platform device was not
showing up under /sys/devices/platform/firmware:scmi instead was
appearing directly under /sys/devices/platform, I noticed the new
faux interface /sys/devices/faux.

Looking through the discussion and the background, I got excited and
took the opportunity to clear all the platform devices under
/sys/devices/platform on the Arm Juno/FVP platforms that are really
faux devices. Only the platform devices created for the device nodes
from the DT remain under /sys/devices/platform after these changes.

All the patches are independent of each other and are part of the series
just to demonstrate the use of macro module_faux_driver() where
applicable. The idea is to get the macro merged first and then push the
individual patches via respective subsystem later.

Changes in v2:
- Dropped all the modalias expect efivars(reason in the patch)
- Defined new helper macro module_faux_driver() and moved most of the
  drivers to use it
- Dropped already queued ASoC and regulator changes
- Link to v1: https://lore.kernel.org/r/20250317-plat2faux_dev-v1-0-5fe67c085ad5@arm.com (local)
