Add dynamic PCI domain _OSC ASL generation codes, supporting both
PCIe and CXL domains.
Dynamic SSDT generation is used to generate a list of ASL device
objects based on FSP outputs (e.g. the SoC/SKU configurations)
and _OSC is a method inside these objects (hence it would be
straightforward to be generated altogether, plus some C codes
managed boot configs could be referenced as well).
This usage is optional. It is helpful for cases where the same
code set supports multiple SKUs/SoCs (difficult to be handled by
one set of static SSDT), and the CPU performance is good enough
to run SSDT generation logics with minimal costs.

reporting the following error:
!!!!! Error: defined(CONFIG_ACPI_SOC_INTEL_SLP_S0_FREQ_HZ)
used at src/include/acpi/acpi.h:457. Symbols of type 'hex'
are always defined.
Since hex Kconfig are always defined there is no need to test it being
defined but also no need to handle zero or non-zero values.
In addition:
1. This config was defined in Meteor Lake specific Kconfig file while
it should actually be define closer to where it is being used (here
soc/intel/common/block/acpi/Kconfig) and only set by the SoC Kconfig.
2. Once moved and under control of `SOC_INTEL_COMMON_BLOCK_ACPI_LPIT'
gating (lpit.c), the Kconfig name needed to be adjusted to better fit
its use.
3. Make Meteor Lake Kconfig sets the config but does not define it
anymore.

Intel platforms use Low Power Idle Table (LPIT) to enumerate platform
Low Power Idle states. There are two types of low power residencies
a) CPU PKG C10 - read via MSR (Function fixed hardware interface)
b) Platform Controller Hub (PCH) SLP_S0 - read via memory mapped
Ref. https://www.uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf
System sleep time (SLP_S0 signal asserted) is measured in ticks,
varies in every platform and based on PMC clock.
