[Asa-dev] [RFC PATCH edk2-platforms v2 1/1] SbsaQemu: Support basic CXL enablement

This adds relevant definitions and descriptions of acpi0016, acpi0017 and CEDT to support CXL.

1) To prevent breaking the original pcie mmio space, this adds exclusive mmio32 & mmio64 space for cxl host.

2) This defines the pcie bus range of cxl host is 0xc0 ~ 0xff, since the pxb-cxl-host as well as cxl components on it would occupy the original pcie buses, the original pcie ecam space should divided some range for pxb-cxl-host.

3) Provide CXL Early Discovery Table that describes the static CXL Platform Components of sbsa-ref, which includes a static CXL Host Bridge structure and a CXL Fixed Memory Window structure which are implemented as two independent space on sbsa-ref: [SBSA_CXL_HOST] & [SBSA_CXL_FIXED_WINDOW].
