Looking at imx6qdl-gw54xx.dtsi I see you have a LVDS panel with
1024x768 resolution.

I sent a patch that allows LDB and HDMI to work simultaneously:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/imx6qdl-sabresd.dtsi?id=d28be499c45e6e16d7a042ce280eb872dc06952b

Can you try to adapt it for imx6qdl-gw54xx.dtsi?

If this still does not help your HDMI output, please try disabling the LVDS.
