tests/kms_chamelium: Capture on type-c
Chamelium uses HPD pulses to signal the need for a receiver reset
using DPMS cycle.Some connectors (e.g. DP over TypeC) have limitations
and will receive just a single such pulse and discard the rest.
This lasts until we disable the mode completetly and only then reenable it.
Receiver reset is always required after we set a new mode, so let's disable
the mode (reset_state() does that) before we switch to a new mode.
With this we will get the HPD pulses reliably for each iteration over
all the supoprted modes.
v2: Correction in code flow (Arek)
