mtd: nand: Create a NAND reset function
When NAND devices are resetted some initialization may have to be done, like for example they have to be configured for the timing mode that shall be used. To get a common place where this initialization can be implemented create a nand_reset() function. This currently only issues a NAND_CMD_RESET to the NAND device. The places issuing this command manually are replaced with a call to nand_reset().
