wifi: rtw89: pci: define PCI ring address for WiFi 7 chips

PCI rings are used to DMA TX/RX packets. The address of WiFi 7 chips are
different from previous ones, so add them according to hardware design.
Another difference is that driver doesn't need to configure BD (buffer
descriptor) RAM table, which is used by hardware to fetch BD ahead before
fetching whole TX data.

A TX ring contains numbers of TX BD (e.g. 512):

   TX BD (buffer descriptor; continual memory)
    +---+---+---+---+     +---+
    |   |   |   |   | ... |   |
    +-|-+---+---+---+     +---+
      |
      | point to TX WD (WiFi descriptor; metadata of a skb data)
      v
    +------+
    |      |
    |      |
    +-|----+
      |
      | point to a skb data
      v
    +------+
    |      |
    |      |
