clk: qcom: dispcc-sm8450: fix DisplayPort clocks

Browse source

On SM8450 DisplayPort link clocks use frequency tables inherited from
the vendor kernel, it is not applicable in the upstream kernel. Drop
frequency tables and use clk_byte2_ops for those clocks.

This fixes frequency selection in the OPP core (which otherwise attempts
to use invalid 810 KHz as DP link rate), also fixing the following
message:
msm-dp-display ae90000.displayport-controller: _opp_config_clk_single: failed to set clock rate: -22
