Bug description:
  === SRU Justification ===
  [Impact]
  i915 crashed when probing for VBT pin. No graphics output after that.

  [Test Case]
  Enable Legacy ROM boot option in BIOS. Screen goes blank.
  Cherrypick fixes can solve the issue. 

  [Fix]
  Handle out of bounds pin value more appropriately.
  Patches from Jani are most refactoring, but the fix we want depends on
  them.
  Patches from Rogrigo are the fixes we want. These patches are also
  picked base on his suggestion,
  https://bugs.freedesktop.org/show_bug.cgi?id=104139#c7
    
  [Regression Potential]
  Low. CNL and CNP are still quite new. These commits are limited to them.
