Subject: [PATCH] drivers: base: power: Remove unused pm_generic_ wrappers

From: "Dr. David Alan Gilbert" <linux@...blig.org>

pm_generic_thaw_early() has been unused since 2016's
commit 294f47ffd55c ("PM / Domains: Remove redundant system PM callbacks")

pm_generic_freeze_late() has been unused since 2019's
commit 3cd7957e85e6 ("ACPI: PM: Simplify and fix PM domain hibernation
callbacks")

Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
