ACPI fixes for 6.6-rc7

Browse Source 
- Fix ACPI initialization ordering on ARM that was changed incorrectly
    during the 6.5 development cycle (Hanjun Guo).
 
  - Make acpi_register_gsi() return an error code as appropriate when
    irq_create_fwspec_mapping() returns 0 on failure (Sunil V L).

 "These fix the ACPI initialization ordering on ARM and ACPI IRQ
  management in the cases when irq_create_fwspec_mapping() fails.

  Specifics:

   - Fix ACPI initialization ordering on ARM that was changed
     incorrectly during the 6.5 development cycle (Hanjun Guo)

   - Make acpi_register_gsi() return an error code as appropriate when
     irq_create_fwspec_mapping() returns 0 on failure (Sunil V L)"

  ACPI: bus: Move acpi_arm_init() to the place of after acpi_ghes_init()
  ACPI: irq: Fix incorrect return value in acpi_register_gsi()
