Merge branches 'acpi-x86', 'acpi-video', 'acpi-soc' and 'acpi-tables'

Merge x86-related ACPI changes, backlight-related ACPI changes, an Intel
SoC (LPSS) ACPI driver update and a missing prototype warning fix
related to ACPI NFIT for 6.5-rc1:

 - Add quirks to work around ACPI tables defects on Lenovo Yoga Book
   yb1-x90f/l and Nextbook Ares 8A (Hans de Goede).

 - Add ACPi backlight quirks for Dell Studio 1569, Lenovo ThinkPad X131e
   (3371 AMD version) and Apple iMac11,3 and stop trying to use vendor
   backlight control on relatively recent systems (Hans de Goede).

 - Add pwm_lookup_table entry for second PWM on CHT/BSW devices in the
   ACPI LPSS (Intel SoC) driver (Hans de Goede).

 - Add nfit_intel_shutdown_status() declaration to a local header to
   avoid a "missing prototypes" build warning (Arnd Bergmann).

* acpi-x86:
  ACPI: x86: Add ACPI_QUIRK_UART1_SKIP for Lenovo Yoga Book yb1-x90f/l
  ACPI: button: Add lid disable DMI quirk for Nextbook Ares 8A
  ACPI: x86: Add skip i2c clients quirk for Nextbook Ares 8A

* acpi-video:
  ACPI: video: Add backlight=native DMI quirk for Dell Studio 1569
  ACPI: video: Stop trying to use vendor backlight control on laptops from after ~2012
  ACPI: video: Add backlight=native DMI quirk for Lenovo ThinkPad X131e (3371 AMD version)
  ACPI: video: Add backlight=native DMI quirk for Apple iMac11,3

* acpi-soc:
  ACPI: LPSS: Add pwm_lookup_table entry for second PWM on CHT/BSW devices

* acpi-tables:
  ACPI: NFIT: Add declaration in a local header
