PCI/P2PDMA: Add missing struct p2pdma_provider documentation



Two fields in struct p2pdma_provider were not documented, which resulted
in the following kernel-doc warning:

  Warning: include/linux/pci-p2pdma.h:26 struct member 'owner' not described in 'p2pdma_provider'
  Warning: include/linux/pci-p2pdma.h:26 struct member 'bus_offset' not described in 'p2pdma_provider'

Repro:

  $ scripts/kernel-doc -none include/linux/pci-p2pdma.h

Fixes: f58ef9d1 ("PCI/P2PDMA: Separate the mmap() support from the core logic")
