src: add --chip_0_size param

[Gateworks]

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.

In src/mtd.c:

I think this will apply for chip 0 and 1. It should be rather easy to actually make it chip 0/1 compatible, just check for i as it is done above with chip_[0|1]_device_path, e.g.

if (i == 0 && md->cfg.chip_0_size) miu->size = md->cfg.chip_0_size; else if (i == 1 && md->cfg.chip_1_size) miu->size = md->cfg.chip_1_size;

Sounds reasonable to me. I don't have any multi-chip boards to test with.
