mtd: nand: fixup for fmr initialization of Freescale NAND controller
There was a bug for fmr initialization, which lead to fmr was always 0x100
in fsl_elbc_chip_init() and caused FCM command timeout before calling
fsl_elbc_chip_init_tail(), now we initialize CWTO to maximum timeout value
and not relying on the setting of bootloader.
