wifi: rtw89: pci: add struct rtw89_{tx,rx}_rings to put related fields

Browse Source 
The new hardware design will expect a continual memory region across
all rings, so a new field will be added to describe the region. To
help the changes, add struct and make changes ahead.

Don't change logic at all.
