[ptxdist] [PATCH v2] ptxd_make_fit_image: Add support for kernel load/entry addresses

[avazquez.dev@gmail.com]

From: AVazquez <avazquez.dev@gmail.com>

Make it possible to specify load/entry addresses for the kernel.
These are required by the FIT image specification, but in some cases
users may not want to include them, so they are made optional.

Also add mandatory "os" property for kernel and ramdisk.
