Add platform specific operations to enable/disable a TSG and use them instead
of directly calling enable/disable APIs
For gm20b/gp106/gp10b we continue to use gk20a_enable_tsg() and
gk20a_disable_tsg() as platform specific operations

Fix a race condition in gk20a_get_channel_from_file() that returns a
channel pointer from an fd: take a reference to the channel before
putting the file ref back. Now the caller is responsible of releasing
the channel reference eventually.
Also document why dbg_session_channel_data has to hold a ref to the
channel file instead of just the channel: that might deadlock if the fds
were closed in "wrong" order.

Remove use of linux specifix header files
<linux/nvhost.h> and <linux/nvhost_ioctl.h>
and use nvgpu specific header file <nvgpu/nvhost.h>
instead
This is needed to remove all Linux dependencies
from nvgpu driver
Replace all nvhost_*() calls by
nvgpu_nvhost_*() calls from new nvgpu library
Remove platform device pointer host1x_dev
from struct gk20a and add struct
nvgpu_nvhost_dev instead

Add the following ioctls
- NVGPU_CHANNEL_IOCTL_GET_TIMESLICE for channel timeslice in us
- NVGPU_TSG_IOCTL_GET_TIMESLICE for TSG timeslice in us
If timeslice has not been set explicitly, ioctl returns the
default timeslice that will be used when programming the runlist
entry.

Remove gk20a_platform dependencies from gk20a.h. This makes
gk20a_platform a Linux platform specific data structure. Add #include
for platform_gk20a.h in the source files that still depend on Linux.

gk20a_err() and gk20a_warn() require a struct device pointer,
which is not portable across operating systems. The new nvgpu_err()
and nvgpu_warn() macros take struct gk20a pointer. Convert code
to use the more portable macros.

Replace the last of the Linux kmem API usage with nvgpu kmem
calls instead. Several places are left alone - allocating the
struct gk20a in particular.
Also one function was updated in the clk code to take a struct
gk20a as an argument so that it could use nvgpu_kmalloc().

Move TSG IOCTL specific code to Linux module. This clears most
Linux dependencies from tsg_gk20a.c.
Move also remaining file_operations declarations from channel_gk20a.h
