Since v5:
- Fix to print an error message instead of a segmentation fault
  when no drive property is specified for a ufs-lu device

Since v4:
Addressed review comment from Stefan Hajnoczi. The fixes are as
follows.
- Keep u->reg fields in host endian (Removed little-endian helper 
  functions from MemoryRegionOps)
- Remove unnecessary NULL checks for g_new and g_malloc0
- Replace DEFINE_PROP_DRIVE_IOTHREAD -> DEFINE_PROP_DRIVE

In case you were wondering, ufs and ufs-lu have been tested for the
following behaviours.
1. Checked ufs device recognition in Windows10 environment
2. Verified ufs device recognition in Ubuntu 22.04 environment
3. Verified io behaviour via fio in Ubuntu 22.04 environment
4. Verified query request via ufs-tools in Ubuntu 22.04 environment

Since v3:
- Replace softmmu_ss -> system_ss in meson

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

Since v1:
- use macros of "hw/registerfields.h" (Addressed Philippe's review
  comments)

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.
