Update the Linux specific code to match the MM API docs in the

This also adds some code to make the CDE page size picking

Earlier implementation of railgate disable config is disabling
runtime pm during pm_init. This is causing multiple issues:
1. gpu rail will be on as soon as nvgpu driver probe is called.
Actual gpu hw init may happen at much later point of time.
2. This is breaking railgate_enable sysfs node functionality.
railgate_enable is not working if runtime pm is disabled.
To avoid all these issues for railgate disable, enable runtime pm
during pm_init and set auto-suspend delay to negative (-1), which
will disable runtime pm suspend calls.
Also fixed following issues along with this:
1. Updated railgate_enable debugfs implementation to use auto-suspend delay.
To disable railgating:
Set auto-suspend delay with negative value(-1) which will disable runtime
pm suspend.
To enable railgating:
Set auto-suspend delay with railgate_delay value.
Also removed redundant user_railgate_disabled gk20a device data and
replaced with can_railgate, where ever it is applicable.
2. Initialized default railgate_delay to 500msec to avoid railgate
on/off transitions with railigate enable from disabled state.
3. Created railgate_residency debug fs node irrespective of can_railgate
initial state. This is helping with the case, where initial state of
railgate state off and then railgate enable is done through sysfs node.

The mechanism of posting events to userspace is OS specific.
In linux this works through poll fd, wherein we can make use
of nvgpu_cond variables to poll and trigger the corresponding
wait_queue.
The post event functionality on QNX doesn't work on poll though.
It uses iofunc_notify_trigger to post the events to the calling
process. As such QNX can't work with nvgpu_cond's.
To overcome this issue, it is proposed to create OS specific
interface function for posting clk arb events. Linux can call
nvgpu_cond based implementation, which makes sense since these
are already initialized and poll'ed in Linux specific code only.
QNX can implement this interface to call iofunc_notify_*
functions, as per its need.

Add NVGPU_IOCTL_CHANNEL_RESCHEDULE_RUNLIST ioctl to reschedule runlist,
and optionally check host and FECS status to preempt pending load of
context not belonging to the calling channel on GR engine during context
switch.
This should be called immediately after a submit to decrease worst case
submit to start latency for high interleave channel.
There is less than 0.002% chance that the ioctl blocks up to couple
miliseconds due to race condition of FECS status changing while being read.
For GV11B it will always preempt pending load of unwanted context since
there is no chance that ioctl blocks due to race condition.
Also fix bug with host reschedule for multiple runlists which needs to
