Tim Harvey a4b86b292a boot: kobs-ng: update kobs-ng for newer kernels
This allows kobs-ng to flash the SPL successfully on the 4.4 kernel used by
the Gateworks IMX boards supporting NAND. The previous version of kobs-ng
worked with the 3.14 kernel but will brick a board making its SPL unbootable
for the 4.4 kernel.

See http://trac.gateworks.com/wiki/ventana/bootloader#nandspl for instructions
on updating the SPL from Linux.

Add --chip_0_size param to override the size of the mtd partition which is
required if the SPL does not occupy the entire partition. For Gateworks
Ventana boards the 'uboot' partition contains both the SPL and uboot.
