The DP wait_hpd_asserted() callback is passed a timeout which
indicates how long we should wait for HPD. This timeout was being
ignored in the MSM DP implementation and instead a hardcoded 500 ms
timeout was used. Fix it to use the proper timeout.

As part of this we move the hardcoded 500 ms number into the AUX
transfer function, which isn't given a timeout. The wait in the AUX
transfer function will be removed in a future commit.

Fixes: e2969ee30252 ("drm/msm/dp: move of_dp_aux_populate_bus() to eDP probe()")
