drivers/uart: Allow the 8250IO driver only on x86
The driver relies on I/O space access functions (inb, etc.), which are
only available on x86.
Rather than explicitly disallowing it on ARM, allow it only on x86.
TEST=Configure for RISC-V, and see that "Serial port on SuperIO" is not
available in the "Generic Drivers" menu anymore.
