Update the debug crash dump to be clearer, more concise and
avoid many of the misformatting issues that have crept in over
the last couple years.
This also changes the debug prints to move from pr_err() in
the Linux kernel to nvgpu_err(). This makes it easier to
filter all nvgpu messages in a log file with a single grep
command.

Originally the order for output was:
1. Dump platform deps (sync-points/host1x stuff)
2. Dump PBDMA status
3. Dump engine status
4. Dump channel status
The updated ordering is:
1. Dump channel status
2. Dump PBDMA status
3. Dump engine status
4. Dump platform deps (sync-points/host1x stuff)
The purpose of this is to put the useful information first and
relegate the less useful info to later in the dump. We naturally
scan downwards and treat stuff at the top as most important.
The end goal is to make the debug dump as useful in as little
time as possible. So instead of making an engineer dig through
a complex jumble of information to find the useful stuff the
hope is that the useful stuff is immediately available.

1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>
2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h

Added debugfs node under ltc directory with name:
intr_illegal_compstat_enable
Enabling/disabling of ltc_illegal_compstat intr is
possible through debugfs node.
Since ltc state is lost with rail gate, this setting is
cached and will be populated during ltc initialization.
