gpu: nvgpu: Generalize BIOS code

Most of BIOS parsing code is not specific to any particular GPU. Move
most of the code to generic files, and leave only chip specific parts
dealing with microcontroller boot into chip specific files.

As most of the parsing is generic, they do not need to be called via
HALs so remove the HALs and change the calls into direct function
calls.

All definitions meant to be used outside BIOS code itself are now in
<nvgpu/bios.h>
