drm/i915: Enable DDI IO power domains in the DP MST path

Commit 62b695662a24 ("drm/i915: Only enable DDI IO power domains after
enabling DPLL") changed how the DDI IO power domains get enabled, but
neglected the need to enable those domains when enabling a DP connector
with MST enabled, leading to

    Kernel panic - not syncing: Timeout: Not all CPUs entered broadcast exception handler
