Subject: [PATCH] iwlwifi: yoyo: remove DBGI_SRAM address reset writing
Git-commit: ce014c9861544bb4e789323d0d8956a5ad262e25
Patch-mainline: v5.18-rc1
References: git-fixes
Due to preg protection we cannot write to this register
while FW is running (when FW in Halt it is ok).
since we have some cases that we need to dump this
region while FW is running remove this writing from DRV.
FW will do this writing.
