arm64: dts: apple: t8103: Add AUDIO_P parent to the SIO_ADMA power domain

The SIO_ADMA is a power domain of the Audio DMA Controller. In addition
to it, the AUDIO_P domain must be on for the controller's MMIO registers
to be accessible.

On t600x and t8112, AUDIO_P is a parent of SIO_ADMA. On t8103, it isn't
so, at least as far as Apple's firmware goes. To make our life easier,
add the parent-child relationship on t8103 also.

arm64: dts: apple: Re-parent ANS2 power domains

Turns out that the APCIE_ST*_SYS domains do hard-depend on ANS2, so
without this they refuse to power up.

arm64: dts: apple: t8103: Add apple,min-state to DCP PMGR nodes

This is required for DCP to boot successfully; it seems if power gating
is allowed, they do not wake up properly.

arm64: dts: apple: t8103: Add PMGR nodes

This adds the two PMGR nodes and all known power state subnodes. Since
there are a large number of them, let's put them in a separate file to
include.
