Disable erase suspend for CFI NOR flash chips

During SpaceCast software development where the rootfs images
was put into the NOR flash, we observed "MTD get_chip(): chip not
ready after erase suspend" error. This resulted in a reboot loop.
For now, we apply OpenWRT patch from
https://dev.openwrt.org/browser/trunk/target/linux/generic/patches-3.19/460-mtd-cfi_cmdset_0002-no-erase_suspend.patch
to disable the flash erase suspend. This avoids the "chip not
ready after erase suspend" error.
