Refactor the aspeed_uart_first() helper to remove its dependency on
AspeedSoCState and make the UART helper APIs more generic.

The function now takes uarts_base as an integer parameter instead of
requiring a full SoC class instance. Corresponding call sites in
aspeed.c and aspeed_soc_common.c are updated accordingly.

No functional change.
