Revert "Revert "Boot up optimization for phoneprocess""

This revert makes telephony start _way_ too late, ranging from 5 to 20 (and
more, depending on model) seconds after the rest of the system, which
leads to all sorts of funky race conditions between boot-time processes

- Automatic language change after manual SetupWizard selection (SIM lang is
  read too late)
- SIM PIN dialog comes up after you've been able to go through lockscreen
- Extraneous "configuration change" dialogs in MSIM hardware
- Collision between encryption and SIM PIN unlocks (sometimes with
  lost input focus, leading to an unusable device)

Applying this patch brings telephony start-up time to sub-second (up to a
couple of seconds) times, which is what's expected. The revert "fixed"
a problem by pushing back the whole phone process for various seconds,
which isn't really acceptable on a phone. :)

This reverts commit 14597f07.
