platform/x86: intel_pmc_ipc: add option to build without ACPI

Introduce a configuration option that allows users to build the
intel_pmc_ipc driver without ACPI support. This is useful for
systems where ACPI is not available or desired.

Based on the discussion from the patch [1], it was necessary to
provide this option to accommodate specific use cases.

arch: x86: add IPC mailbox accessor function and add SoC register access

- Exports intel_pmc_ipc() for host access to the PMC IPC mailbox
- Enables the host to access specific SoC registers through the PMC
firmware using IPC commands. This access method is necessary for
registers that are not available through direct Memory-Mapped I/O (MMIO),
which is used for other accessible parts of the PMC.
