There are currently no platform that are both CONFIG_SYS_NS16550_MEM32
and not (per how the logic was prior to being broken in 0478dac62a9a
("kbuild: Remove uncmd_spl logic")) enabled in CONFIG_DM_SERIAL. We drop
this line out now so that platforms which do use
CONFIG_SYS_NS16550_MEM32 and depending on stage may or may not have
DM_SERIAL set.
Fixes: 0478dac62a9a ("kbuild: Remove uncmd_spl logic")

This means though that we assume all ns16550 implementations have their register value stored in a byte only, either LSB or MSB of a 1-4 byte-wide register (which can (sometimes) be configured with CONFIG_SYS_NS16550_REG_SIZE).
In any case,

I really appreciate you taking the time to debug and suggest a patch, thanks a ton.
Cheers,
Quentin

Applied to u-boot/master, thanks!
