[v2,07/23] hw/ppc/e500: Extract ppce500_ccsr.c

Commit Message

Bernhard Beschow Oct. 5, 2024, 7:45 p.m. UTC

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.
