I feel not only the __setup_param, the whole logic of keep_uart_clocks
are not needed for Module case. Is it true?

Yes, but the 'keep_uart_clocks' is false by default and the function imx_keep_uart_clocks_param()
already has '__maybe_unused', it does NOT impact anything if it is for module build, so I did NOT
add the #ifndef check for them, just to keep code easy and clean.

IMHO do not compile them is a more easy and clean way. Then users
don't have to look into the code logic
which is meaingless for Module case.

BTW, it really does not make any sense to only condionally compile
__setup_parm() but left
the param functions definition to be handled by __maybe_unnused.
They're together part of code, aren't they?
