Hi Randy,

Considering the nature of this driver, and the fact that it provides an
IO space region through the logical PIO framework introduced, it does
not make sense to have it as a loadable module.

A specific issue is that one of our boards uses this host for the UART
console (through 8250-compatible device in BMC), so would want it in the
kernel image.

I will add a note in the commit message and maybe config description
explaining this.

Thanks,
John
