[PATCH 1/2] arm64: dts: imx8qm-mek: Re-enable A72 cluster after ERR050104 workaround

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

The ERR050104 cache coherency workaround for i.MX8QM/8QP has been
merged upstream (d44e08dab27d). The workaround addresses the incorrect
wiring of upper address bits in the A53 subsystem that corrupts TLBI and
IC maintenance operations between A53 and A72 clusters.

Previously the A72 CPUs (cpu at 100, cpu at 101), the cpu-map, and the
cpu1-thermal zone were removed from the MEK board DT to avoid incorrect
cross-cluster coherency maintenance. With the software workaround in place,
restore all deleted nodes.
