pinctrl: cherryview: prevent concurrent access to GPIO controllers
Due to a silicon issue on the Atom X5-Z8000 "Cherry Trail" processor series, a common lock must be used to prevent concurrent accesses across the 4 GPIO controllers managed by this driver. See Intel Atom Z8000 Processor Series Specification Update (Rev. 005), errata #CHT34, for further information.
