gpu: nova-core: vbios: parse structs via zerocopy

Browse source

Replace the unsafe `kernel::transmute::FromBytes` trait implementation
for the `FalconUCodeDescV3`, `PcirStruct`, `BitHeader`, `BitToken`,
`NpdeStruct`, `PciRomHeader`, `PmuLookupTableEntry` and
`PmuLookupTableHeader` structs with the derivable `zerocopy::FromBytes`
trait.

This change eliminates the manual unsafe implementations in favor of a
derivable trait. When this trait is derived, validity checks are
performed at compile time to ensure that the type can safely implement
`FromBytes`.
