gpu: nvgpu: enable big page support for pci
While mapping the buffer, first check if buffer is in
vidmem, and if yes convert allocation into base address
And then walk through each chunk to decide the alignment
Add new API gk20a_mm_get_align() which returns the
alignment based on scatterlist and aperture, and use
this API to get alignment during mapping
Enable big page support for pci by unsetting disable_bigpage
