Instead of patching a single global ops structure depending on the port type, use a separate s3c64xx_serial_ops for the S3C64XX type. This allows us to mark the structures as const. Also split out s3c64xx_serial_shutdown into a separate function now that we have a separate ops structure; this avoids excessive branching control flow and mirrors s3c64xx_serial_startup. tx_claimed and rx_claimed are only used in the S3C24XX functions.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
