This is to weed out accesses to the GPU while it is gated. Otherwise
the accesses are silently dropped or cause a HW hang (on older chips).

Separate the code to load PMU firmware from the software init. This
allows folding ACR and non-ACR PMU software initialization sequences.

pmu_gk20a has a pointer to struct gk20a *. As pmu_gk20a is part of
gk20a, there's no need to have the circular dependency.

Add explict memory barrier wmb() before writing to register values.
Also call writel_relaxed() instead of writel() to skip internal
wmb() call which is conditional on some configs.

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

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.
