ACPI: PM: Simplify and fix PM domain hibernation callbacks
[ Upstream commit 3cd7957e85e67120bb9f6bfb75d81dcc19af282b ]
First, after a previous change causing all runtime-suspended devices
in the ACPI PM domain (and ACPI LPSS devices) to be resumed before
creating a snapshot image of memory during hibernation, it is not
necessary to worry about the case in which them might be left in
runtime-suspend any more, so get rid of the code related to that from
ACPI PM domain and ACPI LPSS hibernation callbacks.
Second, it is not correct to use pm_generic_resume_early() and
acpi_subsys_resume_noirq() in hibernation "restore" callbacks (which
currently happens in the ACPI PM domain and ACPI LPSS), so introduce
proper _restore_late and _restore_noirq callbacks for the ACPI PM
domain and ACPI LPSS.
Fixes: 05087360fd7a (ACPI / PM: Take SMART_SUSPEND driver flag into account)
