Optimized the boot up camping time

Currently the data profiles are only loaded after carrier
config is ready, because the preferred data profile might
have carrier config dependency.

Optimized the data profile loading time by loading the
profiles as soon as SIM is loaded. This will help the
boot up camping time for about 450ms averagely (except
for the very first boot up).
