[PATCH 1/4] HID: amd_sfh: Add DMI quirk and module param to disable interrupts

[Basavaraj Natikar <Basavaraj.Natikar@amd.com>]

From: Helge Bahmann <hcb@chaoticmind.net>

Expose intr_disable as a module parameter to allow runtime override.
Add DMI quirk for ASUSTeK VivoBook TP420UA/TM420UA which requires
interrupts disabled for correct sensor operation.
