wifi: rtw89: add to dump TX FIFO 0/1 for 8852C
MAC maintains TX FIFO to transmit packets with meta data to BB layer. To
debug abnormal transmission, we need to dump the content to dig problem.
Since FIFO of 8852C locates on different address with different size and
need additional switch to enable read operation, this patch adds the
changes accordingly.
