Merge ACPI resource management and ACPI power management chages for
6.1-rc1:

 - Filter out non-memory resources in is_memory(), add a helper
   function to find all memory type resources of an ACPI device object
   and use that function in 3 places (Heikki Krogerus).

 - Add IRQ override quirks for Asus Vivobook K3402ZA/K3502ZA and ASUS
   model S5402ZA (Tamim Khan, Kellen Renshaw).

 - Fix acpi_dev_state_d0() kerneldoc (Sakari Ailus).

 - Fix up suspend-to-idle support on ASUS Rembrandt laptops (Mario
   Limonciello).

* acpi-resource:
  ACPI: resource: Add ASUS model S5402ZA to quirks
  usb: typec: intel_pmc_mux: Use the helper acpi_dev_get_memory_resources()
  ACPI: resource: Skip IRQ override on Asus Vivobook K3402ZA/K3502ZA
  ACPI: LPSS: Use the helper acpi_dev_get_memory_resources()
  ACPI: APD: Use the helper acpi_dev_get_memory_resources()
  ACPI: resource: Add helper function acpi_dev_get_memory_resources()
  ACPI: resource: Filter out the non memory resources in is_memory()

* acpi-pm:
  ACPI: x86: s2idle: Add another ID to s2idle_dmi_table
  ACPI: x86: s2idle: Fix a NULL pointer dereference
  ACPI: x86: s2idle: Add a quirk for ASUSTeK COMPUTER INC. ROG Flow X13
  ACPI: x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7
  ACPI: x86: s2idle: Add a quirk for ASUS ROG Zephyrus G14
  ACPI: x86: s2idle: Add a quirk for ASUS TUF Gaming A17 FA707RE
  ACPI: x86: s2idle: Add module parameter to prefer Microsoft GUID
  ACPI: x86: s2idle: If a new AMD _HID is missing assume Rembrandt
  ACPI: x86: s2idle: Move _HID handling for AMD systems into structures
  ACPI: PM: Fix acpi_dev_state_d0() kerneldoc
