    drm/i915/display: Read DP_ADAPTER_CAP to pass LinkLayer DPCD&EDID tests
    
    4.2.2.1 LinkLayer test states:
    "Verify that Source DUT does the following within 5 seconds after HPD
    being asserted:
    Reads the DPCD Receiver Capability field (DPCD: 00000h:0000Fh)"
    ...
    
    Fail1:
    Source DUT failed to read the DPCD Receiver Capability field (DPCD:
    00000h:0000Fh) through AUX_CH before link training."
    
    Fix this by reading DP_ADAPTER_CAP(0x000F & 0x220F)
