tkudav c95768cad5 gpu: nvgpu: Fix end of VBIOS base ROM ...

Currently, we assume the VBIOS base ROM size is 64KB. We use
this hardcoding to determine when the bios offset lies beyond
the Base ROM.
This assumption fails on Turing when we try to parse the
clock programming tables which are present in expansion ROM
but have an offset < 64KB.
Remove the hardcoding by storing the base rom size.

Also, replace some magic numbers with macros for readability.
