omap_gpmc: Fix handling of FIFOTHRESHOLDSTATUS bit
The OMAP3 TRM is inconsistent about whether the GPMC FIFOTHRESHOLDSTATUS
bit should be set when FIFOPOINTER > FIFOTHRESHOLD or when it is >=
FIFOTHRESHOLD. Apparently the underlying functional spec from which
the TRM was created states that the behaviour is ">=", and this also
makes more conceptual sense.
