If the patch for no host driver works(1024x768/800x600), it will
overwrite 0x18000de0 which BMC used to control DP. Move the patch
later for Host mode only after checking 0x1e6eb0b8[24].

misc: dp: To fix no video when driver not support

Because dp patch for graphics driver is not upstreamed until 2022. Most
distributions doesn't support DP natively. When user try to install OS
using DP, there will be no GUI available.

To fix this problem, we will check vga's reg to see if there is mismatch
between vga current timing and information shared for DP.
