arm64: dts: puma: enable silead touchscreen
Enable the silead based touchscreen labeled EC080D107
Note that the coordinates still need to be scaled. This can be done
by adding this into you xorg.conf:
Section "InputClass"
Identifier "touchscreen"
MatchProduct "silead_ts"
Option "TransformationMatrix" "1.5 0 0 0 0.7 0 0 0 1"
EndSection
