With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in property-entry-test are no longer required.
Remove the unnecessary casts, making the conditions clearer.

This is useful to assign software node reference with arguments
in a common way. Moreover, we have already couple of users that
may be converted. And by the fact, one of them is moved right here
to use the helper.

Add test cases for fwnode_property_count_*() APIs.
While at it, modify the arrays of integers to be size of non-power-of-2
for better test coverage and decreasing stack usage.

Commit c032ace71c29 ("software node: add basic tests for property
entries") introduced a global-out-of-bounds error because it forgot to
add a terminator of "nodes "for software_node_register_nodes() to
process.

This adds tests for creating software nodes with properties supplied by
PROPERTY_ENTRY_XXX() macros and fetching and validating data from said
nodes/properties.
We are using KUnit framework for the tests.
