Subject: [PATCH] rtw88: 8723d: implement flush queue
Git-commit: 7d754f974ac79640c8efda86d35d766704ebaa8e
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430, bsc#1176741
Flush queue is used to check if queue is empty, before doing something
else. Since 8723D uses different registers and page number of
availabl/reserved occupy 8 bits instead of 16 bits, so use a 'wsize' field
to discriminate which rtw_read{8,16} is adopted.
