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
and structures used by nvgpu such that nvhost is replaced by nvgpu.
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.

When outputting debug dump, print the contents of current push buffer
segment.
Also changes the debug dump to use pr_cont when applicable, and dumps
state before recovering in case channel was not loaded to an engine.

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"
