soc/mediatek/mt8196: Add GPUEB support

GPUEB is a micro-processor used for GPU power management. It is also
responsible for controlling GPU DVFS and GPU thermal throttling. This
gpueb load flow adds 47ms to the boot time.

coreboot log:
CBFS: Found 'gpueb_fw.img' @0x84740 size 0x29736 in mcache @0xfffdd374
Loaded (and reset) gpueb_fw.img in 47 msecs.
