intel-pinctrl for v5.5-2

* Fix Baytrail silicon issue by using a global lock
* Fix North community pin names that user will assume their functions
* Convert Cherryview and Baytrail to pass IRQ chip along with GPIO one

The following is an automated git shortlog grouped by driver:

baytrail:
 -  Pass irqchip when adding gpiochip
 -  Add GPIO <-> pin mapping ranges via callback
 -  Update North Community pin list
 -  Really serialize all register accesses

cherryview:
 -  Pass irqchip when adding gpiochip
 -  Add GPIO <-> pin mapping ranges via callback
 -  Split out irq hw-init into a separate helper function
