can: rockchip_canfd: rkcanfd_chip_fifo_setup(): remove duplicated setup of RX FIFO

The rockchip_canfd driver doesn't make use of the TXE FIFO.

Although the comment states that the TXE FIFO is setup, it's actually
a setup of the RX FIFO. The regular setup of the RX FIFO follows.

Remove the duplicated setup of the RX FIFO.
