serial: 8250_mxpcie: add custom handle_irq callback

Browse source

Add a mxpcie-specific handle_irq() implementation for Moxa PCIe serial
ports.

This keeps the interrupt handling self-contained in the driver and
provides a hook point for MUEx50-specific RX/TX paths added in subsequent
patches. The handler processes RX, updates modem status, and handles TX
when THRE is asserted.
