Don't assume 3GPP as active app on CDMA with LTE device

IccCardProxy assumes, that on a CDMA+LTE device, the active app
is the SIM/USIM and not the RUIM/CSIM. However, for voice RUIM/CSIM
is the active app on such a device. All services, like FDN,etc. should
be tied to the active voice app.

telephony: CdmaServiceStateTracker: Get cdma sub. when ruim ready.

This code made the assumption that cdma subscription isn't needed
when on cdma + lte. QCOM devices need to get both to provision
propertly because some SIM records are missing.

This patch adds a system property ro.cdma.subscribe_on_ruim_ready
to specify that CDMA subscription should be requested using NV
once the SIM records have been read.
