gpu: nova-core: add Turing support

Note: This patchset requires "[PATCH v3 2/7] rust: io: always inline functions using build_assert with arguments" in order to compile with CLIPPY.

This patch set adds basic support for pre-booting GSP-RM on Turing.

There is also partial support for GA100, but it's currently not fully implemented. GA100 is considered experimental in Nouveau, and so it hasn't been tested with NovaCore either.

The latest linux-firmware.git is required because it contains the Generic Bootloader image that has not yet been propogated to distros.

Summary of changes:

1. Introduce non-secure IMEM support. For GA102 and later, only secure IMEM is used.
2. Because of non-secure IMEM, Turing booter firmware images need some of the headers parsed differently for stuff like the load target address.
3. Add support the tu10x firmware signature section in the ELF image.
4. Add several new registers used only on Turing.
5. Some functions that were considered generic Falcon operations are actually different on Turing vs GA102+, so they are moved to the HAL.
6. The FRTS FWSEC firmware in VBIOS uses a different version of the descriptor header.
7. On Turing/GA100 LIBOS args struct needs to have its 'size' field aligned to 4KB. So pad the struct to make it 4K.
8. Turing Falcons do not support DMA, so PIO is used to copy images into IMEM/DMEM.
9. Load the Generic Bootloader from disk and use it to boot FWSEC on Turing and GA100.

Changes from v7:
1. Fix unused warnings in some commits that introduce an identifier but don't actually use it until a later commit.
2. Split out the Generic Bootloader code from the PIO code into a separate patch.
3. Removed accidentally included vbios.rs.orig
