Subject: drm/amd/display: Remove assert from PHY state update
Git-commit: d84f5d6562b2f068ec7011f50e702e8a60ec7932
Patch-mainline: v6.1-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 jsc#PED-2849

[Why & How]
In some cases, there are calls to transition from TX_ON to TX_ON. This is
expected, so do not assert. However, these are redundant, so return
prematurely.
