Though CONFIG_ACPI_PPTT is selected by platforms and nor user visible,
it may be useful to support the build with CONFIG_ACPI_PPTT disabled.

This patch adds the missing dummy/boiler plate implementation to fix
the build.

Hi Rafael,

If you are fine with this, can you provide Ack, so that we route this
through ARM64 tree where most of the ACPI PPTT support is present.

Regards,
Sudeep
