serial: 8250_mxpcie: speed up TX using memory-mapped FIFO window
The MUEx50 UART provides a memory-mapped TX FIFO data window along with
a TX FIFO level counter.
Fill the TX FIFO in bulk via the MMIO FIFO window based on available
FIFO space, using uart_port_tx_limited() for the common serial-core TX
handling.
