When exiting rail gate, we reloaded default ZBC values. The correct
behavior is to reload the values.

For GM20B alone, the LTC count is already accounted for the HW logic
for the CBC base calculation from the postDivide address. So SW
doesn't have to explicity divide it by the LTC count in the postDivide
address calculation.

- 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

Add support for booting FECS and GPCCS via faster bootloader method.
We leave this disabled until the bootloader binaries are checked in.

- add rw_semaphore busy_lock for gpu busy() path
- take read lock on busy_lock inside gk20a_busy()
so that all usual requests can execute simultaneously
- write lock can be taken when we need to block all
of the gk20a_busy() calls

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.
