Subject: [PATCH] arm64: dts: qcom: hamoa: Fix OPP tables for all DisplayPort
 controllers

According to internal documentation, the corners specific for each rate
from the DP link clock are:
 - LOWSVS_D1 -> 19.2 MHz
 - LOWSVS    -> 270 MHz
 - SVS       -> 540 MHz (594 MHz in case of DP3)
 - SVS_L1    -> 594 MHz
 - NOM       -> 810 MHz
 - NOM_L1    -> 810 MHz
 - TURBO     -> 810 MHz

So fix all tables for each of the four controllers according to the
documentation, but since DP0 through DP2 have the same entries in their
tables, lets drop the DP1 and DP2 and have all of them share the DP0
table instead. However keep a separate table for the DP3 as it is
different for the SVS, compared to the rest of the controllers.

The 19.2 MHz @ LOWSVS_D1 isn't needed as it's not an actual working
frequency and the controller will never select it. So remove it.
