Currently the core UFS driver does not have a vops to notify when the
device is operational. This commit introduces a hook, which serves to
notify device completing initialization and is ready to accept I/O.
This is required by the FIPS140-2 [1] self integrity test of inline
encryption engine, which must run whenever the host controller is reset.
The code requires sleeping while waiting for I/O to complete and allocating
some memory dynamically, which requires the vendor hook to be restricted.
