ARM: OMAP2+: gpmc: Error out if timings fail in gpmc_probe_generic_child()

Browse Source 
gpmc_cs_set_timings() returns non-zero if there was
an error while setting the GPMC timings. e.g. Timing was too
large to be accomodated with current GPMC clock frequency and available
timing range. Fail in this case, else we risk operating a NOR device
with non compliant timings.
