Subject: [PATCH] rtw88: Use rtw_write8_set to set SYS_FUNC
Git-commit: a4835410995e0a15b40cd4ab13d19e680f5a2602
Patch-mainline: v5.5-rc1
References: jsc#SLE-13430, bsc#1176741
rtw_write8 could modify the values that we do not want
to change, use rtw_write8_set instead to only enable the
bits of sys_func_en
