[PATCH] target/arm: fix s2mmu input size check

[mkei]

From: Keisuke Iida <mkei@sfc.wide.ad.jp>

The maximum IPA size('inputsize') is constrained by the implemented PA size 
that is
specified by ID_AA64MMFR0_EL1.PARange. Please reference Arm Architecture 
Reference
Manual for A-profile architecture "Supported IPA size" on page D5-4788.
