image_type_tezi.bbclass: extend for apalis-imx8
The i.MX8 kernel is currently 20MB and doesn't fit in the hard coded 16MB
boot partition size.
Set the boot partition size dynamically to twice the payload size
rounded up to the next power of 2, but at least to 16MB.
The Apalis iMX8 needs additional firmware for HDMI in the boot partition.
Provide a new MACHINE_BOOT_FILES variable which adds to the list of to be
installed files.
