Currently only cde uses nvgpu_os_linux_ops to set up linux
specific ops. Move nvgpu_os_linux_ops of a gpu to a common
file so that those can be reused for other os ops of that
gpu.

To finish OS unification of the submit path, move the
gk20a_submit_channel_gpfifo* functions to a file that's accessible also
outside Linux code.
Also change the prefix of the submit functions from gk20a_ to nvgpu_.

Update the Linux specific code to match the MM API docs in the
previous patch. The user passed page size is plumbed through
the Linux VM mapping calls but is ultimately ignored once the
core VM code is called. This will be handled in the next
patch.
This also adds some code to make the CDE page size picking
happen semi-intelligently. In many cases the CDE buffers can
be mapped with large pages.

gk20a_submit_channel_gpfifo() supports reading the gpfifo entries from
either a kernel buffer or an userspace buffer in an ioctl. Add two
separate entry points: one for the ioctl and another for any other
kernel use. This shortens the function prototypes and simplifies and
clarifies the call sites slightly.
