[PATCH 06/11] target/arm: Add ARMCacheAttrs to the signature of pmsav8_mpu_lookup

[Tobias Roehmel <quic_trohmel@quicinc.com>]

From: Tobias Röhmel <quic_trohmel@quicinc.com>

Add ARMCacheAttrs to the signature of pmsav8_mpu_lookup to prepare for the Cortex-R52 MPU which uses and combines cache attributes of different translation levels.
