[PATCH v3 00/11] Add support for MT8195 SCP 2nd core

The mediatek remoteproc driver currently only allows bringing up a 
single core SCP, e.g. MT8183. It also only bringing up the 1st 
core in SoCs with a dual-core SCP, e.g. MT8195. This series support 
to bring-up the 2nd core of the dual-core SCP.

v2 -> v3:
1. change the representation of dual-core SCP in dts file and update SCP yaml
2. rewrite SCP driver to reflect the change of dts node
3. add SCP core 1 node to mt8195.dtsi
4. remove redundant call of rproc_boot for SCP
5. refine IPI error message

v1 -> v2:
1. update dt-binding property description
2. remove kconfig for scp dual driver
3. merge mtk_scp_dual.c and mtk_scp_subdev.c to mtk_scp.c
