arm64/mpam: Fix MPAM_ESR intPARTID_range error

hulk inclusion
category: feature
feature: ARM MPAM support
bugzilla: 48265
CVE: NA

--------------------------------

MPAM spec says, when an MPAMCFG register other than MPAMCFG_INTPARTID
is read or written, if the value of MPAMCFG_PART_SEL.INTERNAL is not 1,
MPAMF_ESR is set to indicate an intPARTID_Range error. So we should
set MPAMCFG_PART_SEL.INTERNAL to 1 before reading MPAMCFG_PRI register.
