Pull MFD updates from Lee Jones:
 "Core Framework:
   - Change MFD support status from Supported to Maintained

  New Drivers:
   - Add support for the Intel Platform Management Component Interface
     (PMCI)

  Removed Drivers:
   - HTC PASIC3 LED/DS1WM
   - Toshiba T7L66XB, TC6387XB and TC6393XB TMIO

  New Device Support:
   - Add support for N6000 Flash to Intel M10 BMC PMCI
   - Add support for Lenovo Yoga Tab 3 to Intel CHTWC PMIC

  New Functionality:
   - Provide Reset support to Syscon

  Fix-ups:
   - Explicitly provide missing include files
   - Pass platform type data/info via the SPI/I2C/DT registration
     strategy
   - Lots of DT documentation / adaptions
   - Replace scnprintf() with preferred sysfs_emit()
   - Remove unused / superfluous code
   - Fix some trivial whitesspace / spelling / grammatical issues
   - Replace pm_power_off with new and improved
     register_sys_off_handler() API

  Bug Fixes:
   - Reintroduce RK808-clkout registration - fixing Wi-Fi and Bluetooth
   - Repair the order of AXPxxx IRQ PEK RISE/FALL definitions
   - Refuse to build CS5535 on unsupported UML architectures
   - Fix memory leaks in error return paths
   - Prevent refcount leaks in error return paths"
