Refactor: Split up GPRS into two atoms

Split up GPRS into two atoms: GPRS and GPRS Context.  GPRS will handle
the areas of GPRS network registration, basic GPRS capability detection
and attach / detach.

GPRS Context will handle setting up / activating / deactivating the
indicidual contexts.

This will allow us to use the generic GPRS atom for most devices while
customizing the GPRS context accordingly.
