[PATCH] testimage: Improve sdk handling of TEST_SUITES

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Currently TEST_SUITES is used for both target image and sdk versions which
can be confusing. This introduces TEST_SUITES_SDK for the sdk version of
the code so that the different test sets can be specified independently.
