Revert "anv/icl: Add WA_2204188704 to disable pixel shader panic dispatch"

SLICE_COMMON_CHICKEN3 is a privileged register not accesible from userspace.
This patch silences a simulator warning about it.

We don't need to add this workaround in linux kernel as the WA description
says it's fixed on latest stepping.

This reverts commit 2be60e0c73ed1555a919c5725cc0cab119a2b6de.
