tests: drivers: adc_dma: fix sampling interval failing NXP tests

[heinwessels]

In 6e21ebf the sampling interval was changed, which caused the issue #56070. This is fixed by allowing different boards to specify a sampling period.

Also changed the test_task_with_interval to verify that the supplied interval was used.

@hakehuang would you mind testing this code?

[heinwessels]

@teburd this code will fix half the issue you observed. It should finish the first two tests, and the crash on the third. The other half is caused by a few limitations in the NXP ADC driver, which @hakehuang is fixing, and will likely have a PR ready for soon.

Ah, that looks correct. The crash and failing tests will be fixed by hakehuang.

@heinwessels , one qeustion, how can I create a PR base on your PR?

Can we merge this PR as is? @anangl @teburd It doesn't block CI, as it's not run. Maybe @hakehuang can show that all tests pass if he applies his changes on top of mine.

Other option is that you cherry-pick my commit into a new branch, and then apply your changes on top of that. However, I would prefer the first option. You could even make a commit fixing it on your own branch that's public somewhere, and I cherry-pick it into this PR.

@hakehuang would you mind testing this code?

with your fix and my PR #56120 test log is patch there

[hakehuang]

need work with
#56120

@anangl sorry did not realize that the test was not NXP specific and merged without waiting for your approval, lmk if this was not ok and should be reworked.
