n1sdp:arm arm-bsp: fix tftf tests for n1sdp

This changeset fix the tftf tests issue on n1sdp. Before this change, the tftf tests were getting stuck on n1sdp.
The following changes have been done:

1. There were some tftf tests based on multicore which involve powering up the other cores. These tests were creating
issues and the same thing has already been mentioned in the tests-to-skip.txt file for n1sdp platform in tftf source.
Those tests are skipped while executing tftf and patch has been created.

2. The TFTF_MODE variable added for tftf v2.10 recipe file, as did earlier for tftf v2.9. With the help of this, we can
enable debug or relase mode. The configuration based on this has been added for n1sdp in the corresponding bbappend file.

3. Add PREFERRED_VERSION_tf-a-tests for v2.10.
