Add support for zpos, alpha and blend properties to RZ/G2L DU
driver as the IP supports all these properties.
It is tested by the below modetest commands:
modetest -M rzg2l-du -s 44@42:1920x1080@AR24 -d -P \
37@42:512x300+200+200@XR15
modetest -M rzg2l-du -w {32,37}:alpha:{0,65535}
modetest -M rzg2l-du -w {32,37}:zpos:{0,1}

Tested on RZ/G3E SoC DU using:
modetest -M rzg2l-du -s 55@53:1920x1080@AR24 -d -P 47@53:512x300+200+200@XR15
modetest -M rzg2l-du -w 47:alpha:0
modetest -M rzg2l-du -w 47:alpha:65535
modetest -M rzg2l-du -w 47:zpos:0
modetest -M rzg2l-du -w 47:zpos:1

It's interesting that the driver already handles the alpha, zpos and
blend mode properties set in the state, but doesn't expose those
properties to userspace.

Yes, somehow missed adding alpha, zpos and blend property.
