This commit makes the UFS device support query
and nop out transfer requests.
The next patch would be support for UFS logical

for a new PCI-based UFS device.
The UFS pci device id (PCI_DEVICE_ID_REDHAT_UFS) is not registered
in the Linux kernel yet, so it does not work right away, but I confirmed
that it works with Linux when the UFS pci device id is registered.
I have also verified that it works with Windows 10.

It's important to have at least a basic test that initializes the
device and performs a write followed by a read to verify that I/O is
working. This will all
