drm/amd/display: Add get_dig_frontend implementation for DCEx

2020-12-16T18:27:08Z

Some old ASICs might not implement/require get_dig_frontend helper; in this scenario, we can have a NULL pointer exception when we try to call it inside vbios disable operation. For example, this situation might happen when using Polaris12 with an eDP panel. This commit avoids this situation by adding a specific get_dig_frontend implementation for DCEx.

[why] When display is connected with a native DP port, DP2 mode register value is a don't care. Driver mistakenly reduce max supported lane count to 2 lane based on the don't care value.
