angler: GPS: config LPP_PROFILE=2 as default
LTE Positioning Profile Settings:
0: Enable RRLP on LTE
1: Enable LPP_User_Plane on LTE
2: Enable LPP_Control_Plane on LTE
3: Enable both LPP_User_Plane and LPP_Control_Plane on LTE
Set LPP_PROFILE=2 means UE use RRLP as LTE User Plane protocol and LPP
as LTE Control Plane protocol.
When there is no SIM card in device, live network will switch to a CP
e911 call flow. If the default value LPP_PROFILE=2 instead of 0, then
the LPP CP will work. The AGPS server will locate UE via LPP CP.
But for other carriers, with LPP_PROFILE=2, If network does not support
LPP as LTE Control Plane, LPP CP session will fail. So whether LPP CP
session could go forward only depends on Network capability.
Until now, ATT/TMO/VZW/Sprint/Rogers all have supported LPP CP.
