Patch applied.

I think maybe we can simplify the patch even more using
select GPIO_GENERIC and just specify the different
registers to bgpio_init().

But that can be done as a separate improvement patch, this
definately looks fine.

Maybe you also want something like:

default SERIAL_8250_EXAR

so that the module is by default added as "y" or "m" depending
on what is selected for the parent device?
