cpu/qn908x: use bitarithm_test_and_clear() & fix cb

[maribu]

Contribution description

Previously, the callback was incorrectly passed a channel of zero as argument regardless of the channel that triggered the IRQ. This fixes the issue and also uses bitarithm_test_and_clear() to only iterate over the channels that actually have an IRQ flag set, rather than all channels.

Testing procedure

$ make BOARD=qn9080dk flash test -C tests/periph_timer

for the test application pimped up by #18963
