[HALACPI]: Implement beginning of HAL ACPI support (HalpSetupAcpiPhase0). Tested on VMWare, where it found the FACP, SRAT, RSDT and MCFG and the ACPI Timer at 1008H. BOOT and DBGP are not found (optional features).
[HALACPI]: Support depends on boot loader creating the ACPI BIOS Multi Node structure in MultiFunctionAdapter in the hardware tree. It seems that FreeLdr does this (wow!) correctly!
[HALACPI]: Implement HAL ACPI Table Cache.
[HALACPI]: HAL ACPI Table Overrides from the boot loader are not supported (doubt FreeLdr does this).
[HALACPI]: The next steps are to write the HAL ACPI PnP Driver and HAL ACPI Power Driver.
