Alexander Motin 1f842820e1 Set of improvements to acpi_hp(4) driver.
- Attach only to WMI devices that provide supported GUIDs.  HP Spectre x360
has two WMI devices, only one of which provides the GUIDs.
 - Pass proper device to ACPI_WMI_REMOVE_EVENT_HANDLER() on detach.
 - Improve error WMI handling separating status and data paths.  This allows
to hide sysctls not supported by specific hardware/BIOS.
 - Improve CMI block parser to make it work on HP Spectre x360 laptop.
 - In verbose mode log all unknown events to help futher improvements.
