ARM: dts: rk3288-evb: Add lvds device node on rk3288-evb board

Due to there are only two vop module, that's to say we can't keep
enable eDP / LVDS / HDMI at the same time, so this time we still
keep LVDS device disabled. If you want to enable lvds device,
then you should disable the HDMI or eDP device, and enable the
LVDS device.

And one more thing that eDP panel and LVDS panel can't enable at
the same time, cause both of them have the same enable gpio. If
you still want to do this, there is an hack way that delete the
'enable-gpios' comptabile from 'lvds-panel'.
