gpu: nova-core: firmware: process the GSP bootloader
The GSP bootloader is a small RISC-V firmware that is loaded by Booter
onto the GSP core and is in charge of loading, validating, and starting
the actual GSP firmware.
It is a regular binary firmware file containing a specific header.
Create a type holding the DMA-mapped firmware as well as useful
information extracted from the header, and hook it into our firmware
structure for later use.
The GSP bootloader is stored into the `GspFirmware` structure, since it
is part of the GSP firmware package. This makes the `Firmware` structure
empty, so remove it.
