Now that we have a PPTT parser, in preparation for its use
on arm64, lets build it.

We need to make a choice here. Either PPTT is considered ARM64 only and
we move code and config to drivers/acpi/arm64/Kconfig or we leave it in
drivers/acpi/pptt.c and we add a Kconfig entry in drivers/acpi/Kconfig
(and we make pptt.c compile on !ARM64 - which is what it should be given
that there is nothing ARM64 specific in it).
