scripts: imx: Add support for signed HDMI firmware
Boot header on i.MX8MQ SoC allows embedding signed HDMI firmware
images that are used by mask ROM code during the very early stages of
boot. Since providing that firmware appear to be necessary to enable
SoC's HDMI/DP functionality extend imx-image tool to support this
feature. To do that add code implementing "signed_hdmi_firmware"
keyword, which allows users to specify a path to a binary blob
containing all of the necessary headers and footers as well firmware
data and code sections (this is how such images are provieded by NXP)
