MLK-14548: video: dts: Remove unused regulator

The reg_lcd_3v3 regulator is, theoretically, used by the display
controller eLCDIF as lcd supply.

When enabling the HDMI trasnmitter Sil902x, a gpio pin needed by the
regulator is taken by the HDMI TX as reset pin, so the regulator probe
fails and is never used.

The imx6sx-sdb-lcdif1.dts file is used for HDMI functionality, thus
enabling the HDMI transmitter invalidates any possible use of the
reg_lcd_3v3 regulator.

This patch removes the regulator enablement from the HDMI-specific dts.
