drm/i915/dsi: Fix NULL pointer deref in vlv_dphy_param_init()
Commit 77ba0b856225 ("drm/i915/dsi: convert vlv_dsi.[ch] to struct
intel_display") added a to_intel_display(connector) call to
vlv_dphy_param_init() but when vlv_dphy_param_init() gets called
the connector object has not been initialized yet, so this leads
to a NULL pointer deref:
BUG: kernel NULL pointer dereference, address: 000000000000000c

Hardware name: ASUSTeK COMPUTER INC. T100TA/T100TA, BIOS T100TA.314 08/13/2015

Use to_intel_display(&intel_dsi->base) instead to fix this.
