E3-383: Remove extra git submodules
Restructure git submodules as follows:
- ics-lo-lib: Removed. Files copied to lodistributionApp source directory
- ics-xdriver-core: Removed. Use xdma-dkms rpm package
- ics-xdriver-lib: Removed. Use xdma e3 module
Also, remove empty directories and files not needed in the e3 module.
