[v3,0/3] hw/ufs: Add Universal Flash Storage (UFS) support

Message

Since v2:
Addressed review comment from Stefan Hajnoczi. The main fixes are as follows.
- Use of SPDX licence identifiers
- fixed endianness error
- removed memory leak
- fixed DMA error handling logic


This patch series adds support 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.
