gpu: nvgpu: split vidmem_is_vidmem

Browse Source 
As the vidmem_is_vidmem flag has got two separate meanings in one bit,
split it in two bits into the enabled() API:

Add NVGPU_MM_HONORS_APERTURE bit, which is the same as vidmem_is_vidmem
with its original meaning, and use it to test which aperture bits to
write to hardware.

Add NVGPU_MM_UNIFIED_MEMORY bit, which has the opposite meaning: that
the GPU shares the SoC memory. When this flag is false, the GPU has its
own local video memory.
