The MT8195 SCP is a dual-core RISC-V MCU. Extend the yaml file
to describe the 2nd core as a subnode of the boot core.

The configuration register is shared by MT8195 SCP core 0
and core 1. The core 1 can retrieve the information of configuration
registers from parent node.

I think the commit message would not convince people you put
scp 1 as subnode of scp 0.

Hi Peng,

Thanks for your review. I should give the most reasonable explanation
for why SCP 1 is a subnode.

Adding SCP 1 as a subnode helps to assure finish probing SCP 1
before starting SCP 0 by using of_platform_populate. It's because
that I want to probe SCP 1 as a remoteproc subdevice of SCP 0.
such that when SCP 0 crashed, SCP 0 can reboot SCP 1.
