gpu: nvgpu: make cbc alloc os specific
CBC base needs to be aligned to 64KB. On Linux this is
achieved making compbit backing size multiple of 64KB.
However QNX nvmap alloc function does not allocate
memory aligned to requested size and needs to overallocate
to satisfy alignment requirement. Make cbc alloc function OS
specific to be able to modify QNX code.
Also align cbc base address to 64KB before writing to CBC BASE
register.
