Subject: [PATCH 166/201] imsm: add IMSM_OROM_CAPABILITIES_TPV to nvme orom

Add it to avoid excluding. It has some value for users even if it is
always true for nvme virtual orom.

Rework detail-platform printing code, move printing 3rd party nvmes
to print_imsm_capability (as it should be), but keep it meaningful
only for nvme controllers (NVME and VMD hba types). Pass whole
orom_entry instead of orom there.

Squash code responsible for printing NVME and VMD hbas.
