ENGR00172083 SPI-NOR mx6: fix failed erase uboot ENV on SPI-NOR by MFG tool

In MFG tool will use "flash_eraseall /dev/mtd0" command to erase whole mtd0
partition, but u-boot environment params are stored  in offset 0xc0000 which
exceed the u-boot patition 0x40000, it means the "flash_eraseall" command only
erase u-boot partition, but not environment area. So we need increase the size
of u-boot partition  to 0x100000 as what we remain 1MB for u-boot.
