Add support for the uuu flasher
This adds flasher support for uuu, a utility used by NXP devices for flashing images.
The flasher expects a uuu command list script to be installed in the device rootfs at /usr/share/uuu/flash_script.lst.
The flash_method in deviceinfo to enable it is 'uuu'.
It can be used with pmbootstrap flasher flash_rootfs
after the rootfs image has been built.
