Yan-Hsuan Chuang a5697a65ec rtw88: pci: define a mask for TX/RX BD indexes
Add a macro TRX_BD_IDX_MASK for access the TX/RX BD indexes.

The hardware has only 12 bits for TX/RX BD indexes, we should not
initialize a TX/RX ring or access the TX/RX BD index with a length
that is larger than TRX_BD_IDX_MASK.
