platform/x86/amd/pmf: Initialize and clean up `cb_mutex`
`cb_mutex` was introduced in commit 9e0894d07072e ("platform/x86/amd/pmf:
Enable Custom BIOS Inputs for PMF-TA") to prevent conccurrent access for
BIOS inputs. It however isn't initialized and so on use it may lead to
a NULL pointer dereference.
Add code to initialize on probe and clean up on destroy.
