Merge branches 'pnp', 'acpi-resource' and 'acpica'

Merge a PNP change, new ACPI IRQ management quirks and a small ACPICA
code update for 6.8-rc1:

 - Make pnp_bus_type const (Greg Kroah-Hartman).

 - Add ACPI IRQ management quirks for ASUS ExpertBook B1502CGA and ASUS
   Vivobook E1504GA and E1504GAB (Ben Mayo, Michael Maltsev).

 - Add new MADT GICC/GICR/ITS non-coherent flags and GICC online capable
   bit handling to ACPICA (Lorenzo Pieralisi).

* pnp:
  PNP: make pnp_bus_type const

* acpi-resource:
  ACPI: resource: Skip IRQ override on ASUS ExpertBook B1502CGA
  ACPI: resource: Add DMI quirks for ASUS Vivobook E1504GA and E1504GAB

* acpica:
  ACPICA: MADT: Add new MADT GICC/GICR/ITS non-coherent flags handling
  ACPICA: MADT: Add GICC online capable bit handling
