Subject: drm/msm/dsi: Add phy configuration for MSM8953
Git-commit: 90a06f134c844dd8789f8d39845201289b94c37c
Patch-mainline: v5.16-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Add phy configuration for 14nm dsi phy found on MSM8953 SoC. Only
difference from existing configurations are io_start addresses.
