remoteproc: mediatek: Remove dependency of MT8195 SCP L2TCM power control on dual-core SCP

Browse source

Previously, SCP core 0 controlled the power of L2TCM and dictated that
SCP core 1 could only boot after SCP core 0. To address this constraint,
extracted the power control flow of L2TCM and made it shared
between both cores, enabling support for arbitrary boot order.

The flow for controlling L2TCM power has been incorporated into the
mt8195_scp_before_load() and mt8195_scp_stop() APIs, which are
respectively invoked during the rproc->ops->start() and
rproc->ops->stop() operations. These APIs effectively serve the same
purpose as the rproc prepare()/unprepare() APIs."
