[PATCH v2] powerpc: Refactor board check for quirk

[PATCH v2] powerpc: Refactor board check for quirk

[Kumar Gala]

Refactor the check to determine if the quirk is applicable to the boards
into one inline function so we only have to change one place to add more
boards that the quirks might be applicable to.

Also removed a warning related to unused temp variable.

This commit message could be made better by giving the reader a hint as to
which board is being referred to.
