is_trbe_available() checks for the TRBE support via extracting TraceBuffer field value from ID_AA64DFR0_EL1, and ensures that it is implemented. This replaces the open encoding '0b0001' with 'ID_AA64DFR0_EL1_TraceBuffer_IMP' which is now available via sysreg tools. Functional change is not intended.
