[Impact]
Pantherlake device has VBT (Video BIOS Table) version 266, which reports a
child device config size of 44 bytes. However, the kernel expected only 40
bytes, causing the error:
   ERROR Unexpected child device config size 44 (expected 40 for VBT version 266)

[Fix]
This commit included in v6.18-rc1 fix the issue
4d33c77cf2c3 drm/i915/vbt: Add eDP Data rate overrride field in VBT

[Test]
Boot up PTL system and check dmesg, there should be no the error message like
xe: [drm] ERROR Unexpected child device config size 44 (expected 40 for VBT version 266)

[Where problems could occur]
No, it adds the setting for the latest PTL device with link rate equal to 263.
