8250 devices may modify iotype in their own earlycon setup. For example:
8250_mtk and 8250_uniphier force iotype to be MMIO32. Print earlycon info
after match->setup to reflect actual earlycon info.

But this means you do something which user didn't ask for...

8250_uniphier states that it can only use mmio32
https://elixir.bootlin.com/linux/v5.9-rc4/source/drivers/tty/serial/8250/8250_uniphier.c#L46

For MTK, may be the same case. So they are set in the driver.

+static void __init earlycon_info(struct earlycon_device *device)

Can it be earlycon_pr_info() or earlycon_print_info() ?

Sure. I'll send a v2.
