Merge suspend-to-idle rework material for v5.4.
* pm-s2idle-rework: (21 commits)
ACPI: PM: s2idle: Always set up EC GPE for system wakeup
ACPI: PM: s2idle: Avoid rearming SCI for wakeup unnecessarily
PM: suspend: Fix platform_suspend_prepare_noirq()
intel-hid: Disable button array during suspend-to-idle
intel-hid: intel-vbtn: Avoid leaking wakeup_mode set
ACPI: PM: s2idle: Execute LPS0 _DSM functions with suspended devices
ACPI: EC: PM: Make acpi_ec_dispatch_gpe() print debug message
ACPI: EC: PM: Consolidate some code depending on PM_SLEEP
ACPI: PM: s2idle: Eliminate acpi_sleep_no_ec_events()
ACPI: PM: s2idle: Switch EC over to polling during "noirq" suspend
ACPI: PM: s2idle: Add acpi.sleep_no_lps0 module parameter
ACPI: PM: s2idle: Rearrange lps0_device_attach()
ACPI: PM: Set up EC GPE for system wakeup from drivers that need it
PM: sleep: Drop dpm_noirq_begin() and dpm_noirq_end()
PM: sleep: Integrate suspend-to-idle with generig suspend flow
PM: sleep: Simplify suspend-to-idle control flow
ACPI: PM: Set s2idle_wakeup earlier and clear it later
PM: sleep: Fix possible overflow in pm_system_cancel_wakeup()
