gpu: nova-core: convert falcon registers to kernel register macro

Convert all PFALCON, PFALCON2 and PRISCV registers to use the kernel's
register macro and update the code accordingly.

Because they rely on the same types to implement relative registers,
they need to be updated in lockstep.

nova-core's local register macro is now unused, so remove it.

gpu: nova-core: use the Generic Bootloader to boot FWSEC on Turing

On Turing and GA100, a new firmware image called the Generic Bootloader
(gen_bootloader) must be used to load FWSEC into Falcon memory. The
driver loads the generic bootloader into Falcon IMEM, passes a
descriptor that points to FWSEC using DMEM, and then boots the generic
bootloader. The bootloader will then load FWSEC into IMEM and boot it.
