[ARM] S3C24XX: Split serial driver into core and per-cpu drivers
The S3C2410 serial driver in drivers/serial/s3c2410.c has been
growing bigger with the addition of more variants of this hardware
with the growing Samsung SoCs range. As such, it would be
easier to split this code up into a core and per-cpu drivers to
make driver addition easier, and the core smaller.

Support for the on-chip UARTs on the Samsung S3C24XX series CPUs,
providing /dev/ttySAC0, 1 and 2 (note, some machines may not
provide all of these ports, depending on how the serial port
pins are configured.
- Currently this driver supports the UARTS on the S3C2410, S3C2440,
- S3C2442, S3C2412 and S3C2413 CPUs.
