- Add a sysfs "force_idle" to forcibly idle the GPU
- read on this sysfs will return the current status
0 : not in idle (running)
1 : in forced idle state
"echo 1 > force_idle" will force the gpu into idle
"echo 0 > force_idle" will cause the gpu to resume

gk20a is going to be moved under platform bus, however, the sysfs
interface should remain stable over the transition period. This
patch adds a symlink to keep current interfaces stable.

Currently creation of the load sysfs node is bound to devfreq
profile initialisation, however, this information is useful even
if the scaling is not enabled. This patch modifies the code to create
the sysfs node always.

gk20a_channel_busy is called to host gpu so that gk20a can be accessed.
But it may return error like if gpu fails to be powered on. Always check
the return value of gk20a_channel_busy to avoid illegal access to gk20a.
