Make signal strength parsing common for all modes
Add Support to calculate LTE
level for UI signal bar display
Update the lowest of Evdo/ CDMA dbm value
in phone status instead of using only CDMA dbm

Since some RILs use -1 instead of INVALID_SNR as invalid vlue for
LTE SNR, SignalStrength will not use LTE SNR to check if LTE valid.

The LTE signal strength level is the smaller one
between lte rsrp level and lte snr level if both
rsrp and snr are valid.
The lte snr mapping are
Four bars: SNR >= 45
Three bars: 10 <= SNR < 45
Two bars: -30 <= SNR < 10
One bars: SNR < -30
No bars: No Service
The invalid value of lte snr is changed to INVALID_SNR
from -1, since -1 is a valid value of lte snr.

The new mapping are
Four bars: RSRP >= -95dBm
Three bars: -105 dBm <= RSRP < -95 dBm
Two bars: -115 dBm <= RSRP < -105 dBm
One bars: RSRP < -115 dBm
No bars: No Service

For MR1 LTE isn't supported so the various lte routines aren't used
and are not a stopship.
