ARM: dts: s5pv210: add dummy 5V regulator for backlight on SMDKv210
[ Upstream commit b77904ba177a9c67b6dbc3637fdf1faa22df6e5c ]
Backlight is supplied by DC5V regulator. The DTS has no PMIC node, so
just add a regulator-fixed to solve it and fix dtbs_check warning:
s5pv210-smdkv210.dtb: backlight: 'power-supply' is a required property
