2025-05-13gpu: nova-core: define registers layout using helper macroAlexandre Courbot
Add the register!() macro, which defines a given register's layout and provide bit-field accessors with a way to convert them to a given type. This macro will allow us to make clear definitions of the registers and manipulate their fields safely. The long-term goal is to eventually move it to the kernel crate so it can be used by other drivers as well, but it was agreed to first land it into nova-core and make it mature there. To illustrate its usage, use it to define the layout for the Boot0 (renamed to NV_PMC_BOOT_0 to match OpenRM's naming scheme) and take advantage of its accessors.
