gpu: nvgpu: add compatible VBIOS version for PG189

Browse Source 
Compatible VBIOS version for PG189 is .5A, but it must still boot
with VBIOS .18 and higher.

Added a vbios_compatible_version field in platform descriptor.

Do not boot if VBIOS version is < vbios_min_version.
Otherwise, warn if VBIOS version is not vbios_compatible_version.
