Subject: drm/amd/display: Correct z8 watermark mask
Git-commit: 4f43d753bf9c709ff771eb6dff76269e657555a6
Patch-mainline: v6.7-rc1
References: jsc#PED-3527 jsc#PED-5475 jsc#PED-6068 jsc#PED-6070 jsc#PED-6116 jsc#PED-6120 jsc#PED-5065 jsc#PED-5477 jsc#PED-5511 jsc#PED-6041 jsc#PED-6069 jsc#PED-6071
Correct z8_watermark mask from 16bit to 20bit. Also, do not set dcn35
dprefclk in clk_mgr_construct.
