gpu: nova-core: Extract PMC registers definitions

Move PMC register definitions (NV_PMC_BOOT_0, NV_PMC_BOOT_42) and
their associated implementations from the root regs.rs file into the
gpu module that own them, in the new gpu/regs.rs file.

This follows the same pattern established by previous commits for
GSP, PDISP, PFB, and PBUS registers: register definitions move to
the module that owns them, visibility changes to pub(super), and
cross-module access is provided via pub(crate) helper functions.

Since falcon.rs (outside the gpu module) also reads NV_PMC_BOOT_0 for
its raw value, a pub(crate) helper function boot_0_raw() is added in
gpu.rs to provide that access without exposing the register type
directly.
