target/arm: Correct minor errors in Cortex-A710 definition

Correct a couple of minor errors in the Cortex-A710 definition:
 * ID_AA64DFR0_EL1.DebugVer is 9 (indicating Armv8.4 debug architecture)
 * ID_AA64ISAR1_EL1.APA is 5 (indicating more PAuth support)
 * there is an IMPDEF CPUCFR_EL1, like that on the Neoverse-N1
