Commit afd7f88f1577 ("serial: 8250: move of_serial code to 8250 directory")
moved the serial port driver for Open Firmware platform devices from one
directory to another, but a mixup in Kconfig options resulted in the driver
never being built. This results in runtime failures for some xtensa,
openrisc, and powerpc configurations.
