drm/i915/adlp: Add TypeC PHY TBT->DP-alt/legacy mode switch workaround
Add display workaround # 1309179469 , which fixes a PHY hang when
switching from TBT mode to DP-alt/legacy mode. The workaround also
requires an IFWI/PHY firmware change, before that this change has no
effect (the DKL_PCS_DW5/SOFTRESET flag is always cleared).
