[SRU][N:gke][PATCH 080/106] perf arm-spe: Remove the unused 'midr' field

[Tim Whisonant]

From: Leo Yan <leo.yan at arm.com>

BugLink: https://bugs.launchpad.net/bugs/2117098

The 'midr' field is replaced by the MIDR values stored in metadata (per
CPU wise). Remove the 'midr' field as it is no longer used.
