Tighten lqual table limits check
Previously MAX_GPRS_CS was used for both EDGE and GPRS which means that we waste extra memory in GPRS case. It also leads to misleading name. Let's fix this by introducing separate definitions for GPRS and EDGE cases and use them as appropriate in limit checks. Change-Id: I3ae1ee64ec8e80247b8fe669cc79505b4dadf58f
