x86: Drop bogus __ref / __refdata annotations
The __ref / __refdata annotations used to be needed because of
referencing functions / variables annotated __cpuinit /
__cpuinitdata.
But those annotations vanished during the development of v3.11.
Therefore most of the __ref / __refdata annotations are not needed
anymore. As they may hide legitimate sections mismatches, we
better get rid of them.
