Subject: [PATCH 2/7] ARM: dts: STi: Add gpio polarity for "hdmi,hpd-gpio" property

From: Patrice Chotard <patrice.chotard@...com>

The GPIO polarity is missing in the hdmi,hpd-gpio property, this
fixes the following DT warnings:

arch/arm/boot/dts/stih410-b2120.dtb: Warning (gpios_property): hdmi,hpd-gpio property
size (8) too small for cell size 2 in /soc/sti-display-subsystem/sti-hdmi@...4000

arch/arm/boot/dts/stih407-b2120.dtb: Warning (gpios_property): hdmi,hpd-gpio property
size (8) too small for cell size 2 in /soc/sti-display-subsystem/sti-hdmi@...4000

arch/arm/boot/dts/stih410-b2260.dtb: Warning (gpios_property): hdmi,hpd-gpio property
size (8) too small for cell size 2 in /soc/sti-display-subsystem/sti-hdmi@...4000
