Subject: [PATCH 1/2] wifi: rtw89: 8852c: correct set of IQK backup registers

IQK can change the values of this register set, so need to backup and
restore the values. During we rewrite IQK, the policy is changed. Some
values are controlled and filled by IQK, and don't need to restore after
IQK. Therefore, remove this kind of registers from this array.
