drm/amd/display: Add i2c speed arbitration for dc_i2c and hdcp_i2c
[why]
HDCP 1.4 failed on SL8800 SW w/a test driver use.
[how]
Slow down the HW i2c speed when used by HW i2c.
This request: each acquired_i2c_engine setup the i2c speed needed
and sets the I2c engine for HDCP use at release_engine.
This covers SW using HW i2c engine and HDCP using HW i2c engine.
for dmcu using HW i2c engine, needs add similar logic in dmcu fw.
