memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing
In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY is overwritten by the WEEXTRADELAY value from the device tree and GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device tree. As a consequence, the memory accesses cannot be configured properly when the extra delay are needed for OE and WE. Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the device tree file and prevents GPMC_CONFIG4_OEXTRADELAY being overwritten by the WEXTRADELAY value from the device tree.
