As I see it, the problem here will be different. First, loading dhd is unnecessary if your device has Realtek wifi. The error also applies to this, the 8188eu module seems to be loaded, but cfg80211 is required for the wifi to work, but it crashes due to the incorrect dhd-config. The dhd is only required for Broadcom-based chips.
Question #1: Did you use my Wetek Play project directory as a base? Because then you have to delete this file:
LibreELEC-AML/projects/<YOURPROJECTNAME>/filesystem/usr/lib/modules-load.d/wireless.conf
This will force load dhd even if it is not needed. And that might be the problem for you.
Question #2: Which dtd file did you use in your project?
# Kernel extra targets to build
KERNEL_UBOOT_EXTRA_TARGET="<filename>.dtd"
