Add firmware binaries to qcom-armv8a machine (#1701)

Firmware binaries required for the iq-8275 and iq-9075 platform are not
included by default in images built for qcom-armv8a.
Since the firmware package is not part of the machine’s essential
recommendations, systems may boot without the necessary firmware,
leading to incomplete hardware support at runtime.
This change adds firmware packagegroup to
MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS.
By doing so, the required firmware binaries for the iq-8275 platform are
automatically pulled into the image, ensuring they are available by
default on qcom-armv8a builds.
