acpi: Add PPTT support
This patch adds code to generate Processor Properties Topology Tables (PPTT) compliant to the ACPI 6.4 specification.
- The 'acpi_get_pptt_topology' hook is mandatory once ACPI_PPTT is selected. Its purpose is to return a pointer to a topology tree, which describes the relationship between CPUs and caches. The hook can be provided by, for example, mainboard code.
Background: We are currently working on mainboard code for qemu-sbsa and Neoverse N2. Both require a valid PPTT table. Patch was tested against the qemu-sbsa board.
