[PATCH v2 01/12] drm/msm/dp: fix HPD state status bit shift value

[Jessica Zhang]

The HPD state status is the last 3 bits, not 4 bits of the
HPD_INT_STATUS register.

Fix the bit shift macro so that the correct bits are returned in
msm_dp_aux_is_link_connected().

Fixes: 19e52bcb27c2 ("drm/msm/dp: return correct connection status after suspend")
