ACPI: Keep sub-table parsing infrastructure available for modules
The NFIT driver and now the CXL ACPI driver have both open-coded ACPI table parsing. Before another instance is added arrange for the core ACPI sub-table parsing to be optionally available to drivers via the CONFIG_ACPI_TABLE_LIB symbol. If no drivers select the symbol then the infrastructure reverts back to being tagged __init via the __init_or_acpilib annotation. For now, only tag the core sub-table routines and data that the CEDT parsing in the cxl_acpi driver would want to reuse, a CEDT parsing helper is added in a later change. Cc: "Rafael J.
