Subject: versal-generic: Update machine conf file using gen-machineconf tool

1. Update machine conf file using gen-machineconf tool by parsing
   vck190 xsa.
2. Use TFA_BL33_LOAD for TF-A preloadded bl33 base address.
3. Move variables which changes based on xsa before required
   inclusion file to handle pre-expansion values.
