[Intel-gfx] [PATCH RESEND FOR CI 08/10] drm/i915/dsi: Execute MIPI_SEQ_TEAR_OFF from intel_dsi_post_disable

[Jani Nikula]

From: Hans de Goede <hdegoede at redhat.com>

For v3+ VBTs we should call MIPI_SEQ_TEAR_OFF before MIPI_SEQ_DISPLAY_OFF,
v2 VBTs do not have MIPI_SEQ_TEAR_OFF so there this is a nop.
