Configuring touch controllers to use edge-triggered interrupts is not
recommended as it is very easy to lose an edge when kernel drivers
disable the interrupt for one reason or another, and recovering from
this condition requires workarounds in the kernel.
Unfortunately the example setting up a touchpad used edge-triggered
interrupts, and this set up has been propagating through the boards.
Let's switch the example to use level interrupts instead.

This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'
