Opp rate is used to calc power in thermal framework, so we record
this rate instead of real clock rate.
Devfreq is not ready in target() when use performance governor, so
we need record opp rate in probe().

Last_status is used to calculate dmc's power in thermal control.
If last_status is neithor inited nor kept updated, the power model will
get the wrong status and then the wrong power. And dmc gets wrong
cooling state at last.
Meanwhile this issue reports the warning "core: dev_pm_opp_get_voltage
: Invalid parameters"

When the devfreq cooling device was designed, it was an oversight not to
pass a pointer to the struct devfreq as the first parameters of the
callbacks. The design patterns of the kernel suggest it for a good
reason.
By passing a pointer to struct devfreq, the driver can register one
function that works with multiple devices. With the current
implementation, a driver that can work with multiple devices has to
create multiple copies of the same function with different parameters so
that each devfreq_cooling_device can use the appropriate one. By
passing a pointer to struct devfreq, the driver can identify which
device it's referring to.

can select opp level easy.

The dmc driver supports changing min_freq and max_freq according to
system status and vop bandwidth at present. But even if user changes
governor to userspace, the ddr frequency may also change constantly.
This patch adds a new dmc_ondemand governor which doesn't chang min_freq
and max_freq, it can also support changing ddr frequecy based on usage,
system status and vop bandwidth. So users can set their own frequency by
the userspace governor.

bandwidth is changed, the dmc frequency will also be changed to specified

If new request frequency is greater than old request frequency, update dmc
target frequency immediately. If new request frequency is less than old
request frequency, only update min_freq and max_freq.

Because ddr freq scanning may get clk mutex than get drm general
mutex to get lcdc_type. But when drm status change, drm may get drm
general mutex first and than get clk mutex. This may cause deadlock.
So when get lcdc type we change to use drm_modeset mutex to avoid
deadlock.
