[WHY]
In certain conditions with low pixel clock, some values in DML may go
past the max due to margining for latency hiding. This causes assertions
to get hit.

[HOW]
If the pixel clock is low and some values are high, cap it to the max.

- Driver does not recognize new definitions of psr states.

[why]
Optc needs to know if timing is enabled with ODM or DSC before computing
crc.  Otherwise value computed will be inaccurate. Before this change,
the CRC computed without ODM is not equal to the CRC computed with ODM
for the same timing. This is unexpected as we are driving the same
timing despite of the underlaying hardware setup to achieve it. This is
caused by missing hardware programming sequence to support it.

As it stands, psr has feature flags in dm, stream, and link. Most are
not defined well enough, and different dm layers have different uses for
these same flags.

[How]
We define a new structure called psr_settings in dc_link that will hold
the following psr feature flags:

psr_feature_enable - psr is supported
psr_allow_active - psr is currently active
psr_version - internal psr version supported
psr_frame_capture_indication_req
psr_sdp_transmit_line_num_deadline
The last two flags were moved out of the power module
for the purposes of consolidating psr flags.
Their use is already well-defined.

Psr caps reported by sink will also be stored in dc_link,
in dpcd_caps.psr_caps.
