Subject: [PATCH] pinctrl: cherryview: limit Strago DMI workarounds to version
 1.0

As Google/Intel will fix the BIOS/Coreboot issues with hardcoding
virtual interrupt numbers for keyboard/touchpa/touchscreen controllers
in ACPI tables, they will also update BIOS version number from 1.0
to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ
numbers on Strago boards to those that still carry BIOSes 1.0.
