Split channel debug dump into two phases. In first phase we just copy
the data to a temporary buffer, and in second phase we dump the state
from the temporary buffer.

nvgpu exposes debug dump functionality. Currently this function
misses NULL pointer checks and therefore in cases where the driver
is compiled but the device is disabled, the driver crashes kernel.
This patch adds the missing NULL pointer check.

The return value of gk20a_busy must be checked since it may not succeed
in some cases. Add the __must_check attribute that generates a compiler
warning for code that does not read the return value and fix all uses of
the function to take error cases into account.

To help remove the nvhost dependency from nvgpu, rename ioctl defines

Duplicate some structures as needed.
Update header guards and such accordingly.

Channel and gpfifo allocations are entirely separated from each
other, however, the code here assumes that active channel means
that the channel also has a gpfifo.
This reverts commit a24602f094380539788696d1b1567a4f4d914b17 which
added gpfifo dump. Changing debug dumping to be safe requires
refactoring the channel release code to use proper locking.

Currently the gpu driver assumes that the GPU is a child of host1x.
This is an invalid assumption and therefore we need to get the host1x
device from device tree based on nvidia,host1x property.

debug print "Waiting on syncpt" for gpu channel prints that
channel is waiting for the syncpt without checking the state
of the channel
hence modify this print as follows :
if channel is in "pending acquire" or "on_eng_pending_acquire"
state we print "Waiting on syncpt"
otherwise we print "Waited on syncpt"
