[PATCH 1/3] tools: kwbimage: Add support for NAND_PAGE_SIZE command also for v1 images

[Pali Rohár]

The NAND_PAGE_SIZE command is already supported by mkimage for v0 images,
but not for v1 images.

A38x and A39x BootROM supports reading NAND flash page size from v1 image
in the same way as Kirkwood BootROM from v0 image. It it documented in A38x
and A39x Functional Specification.
