regmap: kunit: Add more cache-drop tests
Extend the testing of cache-drop.

- Added cache_drop_all_and_sync_marked_dirty(). If all registers are
  dropped from the cache a regcache_mark_dirty() followed by
  regcache_sync() should not write anything because the cache is empty.

- Added cache_drop_all_and_sync_no_defaults(). This is similar to
  cache_drop_all_and_sync_marked_dirty() except that regcache_mark_dirty()
  is NOT called. All registers were dropped so regcache_sync() should not
  write anything.

- Added cache_drop_all_and_sync_has_defaults(). This is the same as
  cache_drop_all_and_sync_no_defaults() except that the regmap has a
  table of default values.

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 reStructuredText 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.
