This serial port is used on all 8xx, many 82xx, and some 85xx chips.
The driver requires that the port has already been set up by the firmware
and/or platform code.

1. Search the entire compatible list for serial devices.
The serial code previously did a simple strcmp on the compatible
node; this fails when the match string is not the first compatible
listed. Use dt_is_compatible() instead.
2. Don't call serial_edit_cmdline if getc isn't defined.

The bootwrapper requires a serial driver to allow cmdline editing
and information reporting on the console. This driver is required
by platforms that boot a zImage and use the MPSC for the console.

Add serial console support for non-OF systems. There is a generic serial
console layer which calls a serial console driver. Included is the serial
console driver for the ns16550 class of uarts. Necessary support routines
are added as well.
