arm: mach-k3: am642: Update MAIN UART1 serial alias from 3 to 1
The upstream device tree changed the serial alias for MAIN UART1 from
serial3 to serial1. Update the board initialization code to match this
change by modifying the UCLASS_SERIAL sequence number lookup.
This ensures proper pin control configuration for the UART used by
system firmware (SYSFW).
