dts: xtensa: intel: Remove non-existent power domains from ACE30 PTL DTS

This patch removes definitions of power domains from the ACE30 PTL DTS
file that do not exist in the actual hardware.

The following power domain nodes have been removed:
- 'ml1_domain' with a bit-position of <13>
- 'io3_domain' with a bit-position of <11>
- 'io2_domain' with a bit-position of <10>

These nodes were previously included in the DTS file but do not
correspond to any physical power domain in the ACE30 PTL hardware. Their
presence in the DTS could lead to confusion and misconfiguration, as the
software might attempt to interact with non-existent hardware features.

By removing these nodes, the DTS now accurately reflects the hardware
capabilities of the ACE30 PTL platform, ensuring that the power
management infrastructure within the firmware operates based on the
correct hardware configuration.
