I converted the _FIXED macros to register! entries, and now the only thing I need now is:

/// IFR signature: ASCII "NVGI" as a little-endian u32.
const NV_PBUS_IFR_FMT_FIXED0_SIGNATURE_VALUE: u32 = 0x4947564E;
/// ROM directory signature: ASCII "RFRD" as a little-endian u32.
const NV_ROM_DIRECTORY_IDENTIFIER: u32 = 0x44524652;
/// Offset of the NV_PMGR_ROM_ADDR_OFFSET register in IFR Extended section
const IFR_SW_EXT_ROM_ADDR_OFFSET: usize = 4;
/// Size of Redundant Firmware Flash Status section
const RFW_FLASH_STATUS_SIZE: usize = 4096;

The second two I made up, so they can't be imported.  NV_PBUS_IFR_FMT_FIXED0_SIGNATURE_VALUE comes
from dev_bus.h as you said, but NV_ROM_DIRECTORY_IDENTIFIER comes from kernel_gsp_vbios_tu102.c, so
I don't think it can be imported either.

Also, what tree is your DIFF for?
