[PATCH v4 08/26] hw/ppc/e500: Extract ppce500_ccsr.c

[Bernhard Beschow <shentey@gmail.com>]

The device model already has a header file, so extract its implementation into
an accompanying source file like other e500 devices. While at it rename the
header file to reflect the name of the structure defined there.

This commit is also a preparation for the next commit.
