Subject: [PATCH] iwlwifi: yoyo: check for the domain on all TLV types during init
Git-commit: e701da0c2320148a378ed1d191b6c4f7e8e82c4c
Patch-mainline: v5.6-rc1
References: jsc#SLE-13430

Now that we don't have dynamically changing domains anymore, we can
simply skip all the TLVs with domains that are not enabled.  To do so,
remove the checks from the functions that handle the TLVs when a
timepoint is reached to the top allocation function.
