Reduce the number lines to output by only testing for intervals 0..15 to speed up the test. In addition, run each test case 128 repetitions (it is still faster than before) to give some confidence the short relative set actually succeeded.

19035: cpu/nrf5x_common: implement timer_set() r=maribu a=maribu ### Contribution description The fallback implementation of timer_set() in `drivers/periph_common` is known to fail on short relative sets. This adds a robust implementation. ### Testing procedure Run `tests/periph_timer_short_relative_set` at least a few dozen times (or use #19030 to have a few dozen repetitions of the test case in a single run of the test application). It should now succeed. ### Issues/PRs references None Co-authored-by: Marian Buschsieweke <marian.buschsieweke@ovgu.de>

However, this so far did not take `TEST_ON_CI_BLACKLIST` and `TEST_ON_CI_WHITELIST` into account, resulting in tests being executed for boards which they are not available. This should fix the issue. ### Testing procedure #### Expected to fail ``` $ make BOARD=nrf52840dk -C tests/gcoap_fileserver test/available $ make BOARD=microbit -C tests/log_color test/available ``` (On `master`, they succeed, but fail in this PR.) #### Expected to succeed ``` $ make BOARD=native -C tests/gcoap_fileserver test/available $ make BOARD=nrf52840dk -C tests/pkg_edhoc_c test/available $ make BOARD=nrf52840dk -C tests/log_color test/available ``` (Succeed in both `master` and this PR.) ### Issues/PRs references None Co-authored-by: Marian Buschsieweke <marian.buschsieweke@ovgu.de>

19087: cpu/qn908x/periph_timer: Implement timer_set() r=kaspar030 a=maribu ### Contribution description This fixes test failures in tests/periph_timer_short_relative_set. Note: This differs a bit from the implementation in e.g. nRF5x or STM32 in that it always briefly pauses the timer. The issue is that when running the timer can take a few ticks to actually react to the new compare target. So even if the previously written target is still in the future, the timer may not fire anyway. Pausing the timer while setting and setting the target at least one higher than the current count reliably triggers the IRQ. ### Testing procedure Run `tests/periph_timer_short_relative_set` at least a few dozen times (or use #19030 to have a few dozen repetitions of the test case in a single run of the test application). It should now succeed. ### Issues/PRs references None Co-authored-by: Marian Buschsieweke <marian.buschsieweke@ovgu.de>
