Revert "parisc/stifb: Keep track of hardware path of graphics card"

This reverts commit 860e44f2 which is
commit b046f984 upstream.

It breaks the Android kernel ABI and is not needed for Android devices,
so it is safe to revert for now.  If it is determined that it is needed
in the future, it can be brought back in an abi-preserving way.
