Revert "mediatek: mt8365: enable HW_ASSISTED_COHERENCY"

HW_ASSISTED_COHERENCY can only be used on processors that use the ARM DynamIQ Shared Unit (DSU). In that case, the power-down and power-up sequences are mostly managed in hardware, reducing complexity of the software operations.

From 1, DSU is not supported on Cortex-A53, which is the CPU from MT8365 SoC.

This reverts commit 5bff1a59.
