arm64: dts: ti: k3-j722s-evm: Add HDMI_LS_OE gpio-hog
Add the gpio hog for HDMI_LS_OE for HDMI ESD device TPD12S016PWR.
Without this signal pulled up, TPD12S016PWR is unable to pass through
the I2C request to HDMI connector which results in EDID not being read.
After that fallback mode 1024x768 and smaller resolutions are added
as valid modes.
Pull up the control pin HDMI_LS_OE to get EDID working.
