HFP/HBP/HSA/EOT_PACKET modes in Exynos DSI host specifies
0 = Enable and 1 = Disable.
The logic for checking these mode flags was correct before
the MIPI_DSI*_NO_* mode flag conversion.
Fix the MIPI_DSI*_NO_* mode flags handling.
Fixes: 0f3b68b66a6d ("drm/dsi: Add _NO_ to MIPI_DSI_* flags disabling
features")
