There is new field "edp pipe joiner feature" size of 2 bytes in the
eDP VBT block. Each bit represent panel number to be enable/disable
for this feature.

Default value:
For ARL platform, 0x0000 to keep the feature disabled by default.
Xe3lpd onwards, 0xFFFF to keep the feature enable by default by VBT.

Bspec: 20142
