gpu: nvgpu: add PRAMIN support for mem accessors
To support vidmem, implement a way to access buffers via the PRAMIN
window instead of just kernel-mapped sysmem buffers for iGPU as of now.
Depending on the buffer aperture, choose between the two access types in
the buffer memory accessor functions.
vmap()/vunmap() pairs are no-ops for buffers that can't be cpu-mapped.
Two uses of DMA_ATTR_READ_ONLY are removed in the ucode loading path to
support writing to them too via the indirection in addition to cpu.
