[PATCH] drm/pl111: Fix defined-but-not-used warnings in COMPILE_TEST mode.

[Eric Anholt <eric@anholt.net>]

Our probe function is guarded by CONFIG_ARM_ABMA, so these functions
end up unused if it's not enabled.  We do want to be able to build DRM
drivers on inapplicable platforms, for refactor testing purposees.
