Remap MSM8660 stock unsolicited RIL responses

The proprietary RIL produces responses that are either obsolete
(and shold be ignored) or do not match their corresponding values in
frameworks/base/telephony/java/com/android/internal/telephony/RILConstants.java.
This patch remaps the mismatched response types and
ignores the obsolete ones.
