ACPI: x86: Force enabling of PWM2 on the Yogabook YB1-X90

Browse Source 
The PWM2 on YB1-X90 tablets is used for keyboard backlight control but
it is disabled in the ACPI DSDT table. Add it to the override_status_ids
list to allow keyboard function control driver
(drivers/platform/x86/lenovo/yogabook.c) to use it.
