[PATCH 0/4] serial: 8250: Add AN7581 UART support

This is a new version of [1] to support UART driver for
Airoha SoC.

One additional function was needed serial8250_get_baud_rate()
for the driver to work correctly for baud rate calculation.

While at it also try to clarify a long standing issue with
new UART driver when adding new ids for uart_config[].

Changes compared to [1]:
- Fix all formal error
- Use better compatible names
- Drop unneeded header
- Drop usage of irq (it's filled by the generic function)
- General code cleanup and reorg
- Split to patch and add the UAPI map patch
