ARM: OMAP2+: nand: reorganize gpmc timing values
This patch removes omap2_nand_gpmc_retime() which was used to quirk some timing values before gpmc_cs_set_timings(). Due to recent changes, gpmc_cs_set_timings() has evolved so that there is no more need for a retime function. To keep the gpmc configuration consistent for legacy board files, this patch also adds oe_on and we_on to nand_default_timings[] as they would be by the retime function.
