gpu: nova-core: support header parsing on Turing/GA100

Browse Source 
The Turing/GA100 version of Booter is slightly different from the
GA102+ version.  The headers are the same, but different fields of
the headers are used to identify the IMEM section.  In addition,
there is an NMEM section on Turing/GA100.
