Subject: drm/amd/display: Fix typo in enable and disable symclk_se
Git-commit: ec4b70db47e7925c804d8140c3b1f6a62366cb55
Patch-mainline: v6.6-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

[Why & How]
Symclk should be based on link_enc_inst, and symclk_fe_sel should be based
on stream_enc_inst.
