QS/PW: Check for mobile data instead of telephony permissions (2/2)

For QuickSettings and Power Widget check if there is
ConnectivityManager.TYPE_MOBILE network avaialbe directly instead of relying
on a checking for the PackageManager.FEATURE_TELEPHONY permission.  Some
devices like tilapia (Nexus 7 GSM) has mobile data but does not set the
telephony permission.

Patchset 2:
	- Have power widget use the same logic as quicksettings to check for
	  mobile data

Fixes: CYAN-803
DataUsageSummary: fix mobile data usage display for sim-less devices

- Don't assume the device has a sim card. Check for a phone number
  instead. Otherwise the mobile data usage screen will not show up
  on sim-less CDMA devices.

DataUsageSummary: fix mobile data usage display for GSM devices with no number

Some providers don't write phone number onto SIM card causing the
phone number check introduced in the partially reverted commit to fail.
Re-introduce the original check with the "or" condition.

This partially reverts commit 4c51b45355b9d6fed973f946738bf455a8b7c9ea.
