Log Message:
Add ACPI support (enable with -DEFIBOOT_ACPI, currently disabled).

When UEFI reports that ACPI tables are available, generate a DTB with
compatible string "netbsd,generic-acpi" and pass this to the booted
kernel.

The DTB contains a /chosen property "netbsd,acpi-root-table" that contains
the physical address of the ACPI RSDP, along with a special /acpi node
with compatible string "netbsd,acpi" for the kernel to attach an acpi(4)
device driver.
