Pull vfio updates from Alex Williamson:

 - Extend vfio-pci 8-byte read/write support to include archs defining
   CONFIG_GENERIC_IOMAP, such as x86, and remove now extraneous #ifdefs
   around 64-bit accessors (Ramesh Thomas)

 - Update vfio-pci shadow ROM handling and allow cached ROM from setup
   data to be exposed as a functional ROM BAR region when available
   (Yunxiang Li)

 - Update nvgrace-gpu vfio-pci variant driver for new Grace Blackwell
   hardware, conditionalizing the uncached BAR workaround for previous
   generation hardware based on the presence of a flag in a new DVSEC
   capability, and include a delay during probe for link training to
   complete, a new requirement for GB devices (Ankit Agrawal)
