[PATCH v2 1/2] binman: add a new entry type for generating a data file which is passed to mkimage with -n

[Alice Guo (OSS)]

From: Alice Guo <alice.guo at nxp.com>

i.MX95 needs to pass some commands defined in enum imx8image_cmd to
imx8image_copy_image() function, so add a new entry type nxp-config to
generate a data file includes theses commands in plain text format.

+This entry is used to generate a data file. Each line of this data file is a
