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.

On imx6SX SDB eLCDIF driver cannot coexist with CAAM driver. The cause
seems to be an ipg clk that failes to be identified by the CAAM driver.
This patch disables the CAAM driver by setting its status to "disabled"
in the dts used for obtaining LCDIF functionality.

The PIN is conflicted with CSI camera. Need to disable CSI to make lcdif work.
