Before calling prod settings functions, check for
availability of those functions.
Similar check is extended for get_clk_freqs.

Define specific QoS notifier for common clk framework
and protect it with CONFIG_COMMON_CLK
This new API will first get min/max requirements from
pm_qos and set min/max freq values in devfreq
A call to update_devfreq() will then ensure that
new estimated frequency is clipped appropriately
between min and max values
This also ensures that frequency is set along with
all the book-keeping
Add below platform specific notifier callback and use it
with pm_qos_add_notifier()
int (*qos_notify)()
If qos_notify is set, then only register the callback
We currently support only one qos_id which is treated
as notifier for min frequency
Remove dependency on qos_id, and use appropriate QoS
APIs like pm_qos_read_min/max_bound()
Store devfreq's min/max frequency in struct gk20a
for reference

When thermal throttling triggers gpcclk clock
changes, devfreq driver need to have call back
for get_cur_freq to get current gpu frequency.
With out this change, "17000000.gp10b/cur_freq"
interface won't show the current gpcclk frequency,
when thermal throttling triggers gpcclk frequency
changes.

Use struct device instead of struct platform_device wherever
possible. This allows adding other bus types later.

We currently call gk20a_pmu_load_update() before calling
update_devfreq()
But it is possible to disable governor and set a
constant/max frequency.
In that case we will unnecessarily keep executing
gk20a_pmu_load_update() for each submit
Hence. move gk20a_pmu_load_update() to gk20a_scale_get_dev_status()
so that we call gk20a_pmu_load_update() only when we really
have to scale the frequency

o QoS notifier
Refresh the gpu load query because we may update the emc target
if gpu load changed.
o tegra_postscale()
Scaling the emc clock to a new target may be necessary
if the gpu load changed at low gpu frequencies.

Reading the load value may increase CPU power consumption
temprorarily. In most cases we are ok with a value that
was read a moment earlier.
This patch introduces a software shadow for gpu load. The shadow
is updated before starting scaling and all scaling code paths use
the sw shadow.

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.
