drm/i915: add basic MIPI DSI output support
This does not include any panel specific sub-encoders yet. v2: Fix fixed mode handling (Daniel) v3: Mostly based on Ville's review comments. - Fix MIPI_HS_TX_TIMEOUT. - DPI_ENABLE only for video mode. - Drop ULPS usage for now, use DEVICE_READY only. - Set MIPI_INIT_COUNT based on txclkesc.
