platform-drivers-x86 for 4.9-1

Cleanups, refactoring, and a couple bug fixes.
 
 intel_pmc_core:
  - avoid boot time warning for !CONFIG_DEBUGFS_FS
 
 intel_pmc_ipc:
  - Convert to use platform_device_register_full
 
 asus-wmi:
  - Filter buggy scan codes on ASUS Q500A
 
 toshiba_bluetooth:
  - Decouple an error checking status code
 
 toshiba_haps:
  - Change logging level from info to debug
  - Split ACPI and HDD protection error handling
 
 asus-laptop:
  - get rid of parse_arg()
 
 asus-wmi:
  - fix asus ux303ub brightness issue
 
 toshiba_acpi:
  - Fix typo in *_cooling_method_set function
  - Change error checking logic from TCI functions
  - Clean up variable declaration
