Add sanity checking to some test harness functions to help catch bugs
in the test code. This consists of checking the range of some arguments
and checking that reads from the dummy regmap succeed.
Most of the harness code already had sanity-checking but there were a
few places where it was missing or was assumed that the test could be
trusted to pass valid values.

Add a mock firmware file that emulates what the firmware build tools
would normally create. This will be used by KUnit tests to generate a
test bin file.
The data payload in a bin is an opaque blob, so the mock bin only needs
to generate the appropriate file header and description block for each
payload blob.
