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.

Set audio mode after accepting the call

Set the audio mode to incall immediately after accepting the call and not wait
till call is reported as ACTIVE by RIL. This is done to speed up time taken for audio
to set up the voice path

(CM change: Remove calls to Rlog, since we haven't imported that yet)
