When switching between 2 dongles/adapters it is possible
to have the same resolution with different link configuration.
Even though the pixel clock could be the same on replug, the
vco clock could be different depending on the link
configuration. Since the dp driver only exposes limited clocks
to the clock framework, in this specific scenario, the clock
driver is unable to recognize the change in source clock rate
and ends up skipping the clock reconfiguration.
This change adds support to park the pixel clocks on disable,
thereby forcing a reconfiguration on subsequent replug even
if the pixel clocks are the same.

Add safety checks to check for dp link and core clocks before accessing
the main control registers during dp teardown or dp setup.

This change adds the support to request the dp link clk rate
through the mmrm driver. In the case the system can not
support the rate, user space is notified of the failure and
dp is diconnected.

Add runtime_pm ops support in drm driver instead
of direct sde_power_resource_enable/disable call.
It allows drm driver to use runtime pm refcount logic
to track the resources instead of custom implementation.
The change also removes the NRT_CLIENT support from
sde_power_handle code to simplify it further.
