submodule berkeley-db-1.xx @ fe920af maybe not exist in origin repo

[ghmole]

git submodule update failed

[Basicname]

My solution (lv_bindings also):

1. remove 'lib/berkeley-db-1.xx' module
2. manually run git clone https://github.com/pfalcon/berkeley-db-1.xx -b embedded and move it to lib/
3. another potential problem: esp-dl or esp-code-scanner not found manually download files under "esp-who" repo, you will find these files under components/

I built it successfully in this way with idf 4.4
