Series serial: 8250_dw: describe the Allwinner H616 UART configuration |

Commit Message

James Hilliard Oct. 23, 2026, 7:33 a.m. UTC 
The Allwinner H616 UART has 256-byte FIFOs but does not implement the
DesignWare component parameter register used to discover their size.

Add a compatible to identify this integration and its fixed FIFO
configuration. Retain snps,dw-apb-uart as a fallback.
