clk: qcom: dispcc-sm8550: fix DisplayPort clocks

[ Upstream commit e90b5139da8465a15c3820b4b67ca9468dce93b4 ]

On SM8550 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
