[Brett Creeley <brett.creeley@amd.com>]

This series contains various clean-ups, improvements, and support
for multiple dirty tracking regions. The majority of clean-up and
improvements are in preparation for the last patch in the series,
which adds support for multiple dirty tracking regions.

Changes:

v2:
- Make use of BITS_PER_BYTE #define
- Use C99 style for loops
- Fix subject line to use vfio/pds instead of pds-vfio-pci
- Separate out some calculation fixes into another patch
  so it can be backported to 6.6-stable
- Fix bounds check in pds_vfio_get_region()
