You misunderstood. I don't propose to remove HAVE_ACPI_TABLES.
HAVE_ACPI_TABLES remains per-board characteristic.
The only thing I remove is GENERATE_ACPI_TABLES which is user-visible
This way presence of ACPI-tables is determined by board porter based on
the need and availability of ACPI tables

Right now we're at opposite end when you almost have to use genetic
algorithm to find which configuration works.
