ACPI updates for 5.2-rc1

Browse source 
- Convert the ACPI documentation in the kernel source tree to the
    .rst format and split it into the admin guide, driver API and
    firmware guide parts (Changbin Du).
 
  - Add a PRP0001 usage example to the ACPI documentation (Thomas
    Preston).
 
  - Switch over the users of the acpi_dev_get_first_match_name()
    library function which turned out to be problematic to a new,
    better one called acpi_dev_get_first_match_dev() (Andy Shevchenko,
    YueHaibing).
 
  - Update the ACPICA code in the kernel to upstream release 20190405
    including:
    * Null pointer dereference check in acpi_ns_delete_node() (Erik
      Schmauss).
    * Multiple macro and function name changes (Bob Moore).
    * Predefined operation region name fix (Erik Schmauss).
 
  - Fix hibernation issue on systems using the Baytrail and
    Cherrytrail Intel SoCs introduced during the 4.20 development
    cycle (Hans de Goede).
 
  - Add Sony VPCEH3U1E to the backlight quirk list (Zhang Rui).
 
  - Fix button handling during system resume (Zhang Rui).
 
  - Add a device PM diagnostic message (Rafael Wysocki).
 
  - Clean up the code, comments and white space in multiple places
    (Bjorn Helgaas, Gustavo Silva, Kefeng Wang).

Pull ACPI updates from Rafael Wysocki:
 "These rearrange the ACPI documentation by converting it to the .rst
  format and splitting it into clear categories (admin guide, driver
  API, firmware guide), switch over multiple users of a problematic
  library function to a new better one, update the ACPICA code in the
  kernel to a new upstream release, fix a few issues, improve power
  device management diagnostics and do some cleanups.

  Specifics:

   - Convert the ACPI documentation in the kernel source tree to the
     .rst format and split it into the admin guide, driver API and
     firmware guide parts (Changbin Du).

   - Add a PRP0001 usage example to the ACPI documentation (Thomas
     Preston).

   - Switch over the users of the acpi_dev_get_first_match_name()
     library function which turned out to be problematic to a new,
     better one called acpi_dev_get_first_match_dev() (Andy Shevchenko,
     YueHaibing).

   - Update the ACPICA code in the kernel to upstream release 20190405
     including:
       * Null pointer dereference check in acpi_ns_delete_node() (Erik
         Schmauss).
       * Multiple macro and function name changes (Bob Moore).
       * Predefined operation region name fix (Erik Schmauss).

   - Fix hibernation issue on systems using the Baytrail and Cherrytrail
     Intel SoCs introduced during the 4.20 development cycle (Hans de
     Goede).

   - Add Sony VPCEH3U1E to the backlight quirk list (Zhang Rui).

   - Add a device PM diagnostic message (Rafael Wysocki).

   - Clean up the code, comments and white space in multiple places
