HID: amd_sfh: Add functionality to clear interrupts

[ Upstream commit fb75a3791a8032848c987db29b622878d8fe2b1c ]

Newer AMD platforms with SFH may generate interrupts on some events
which are unwarranted. Until this is cleared the actual MP2 data
processing maybe stalled in some cases.

Add a mechanism to clear the pending interrupts (if any) during the
driver initialization and sensor command operations.
