[Intel-gfx] [PATCH v7 05/23] drm/i915/icl: Make common DSI functions available

[Jani Nikula]

From: Madhav Chauhan <madhav.chauhan at intel.com>

This patch moves couple of legacy DSI functions to header and common DSI
files so that they can be re-used by Gen11 DSI. No functional change.

v2 by Jani:
 - Move intel_dsi_msleep() to intel_dsi_vbt.c
