skylake: only generate ACPI cpu entries once
The acpi_fill_ssdt_generator function pointer is evaluated for
each device. As there are multiple cpus in the system the
acpi_fill_ssdt_generator was being called more than once creating
duplicate ACPI entries because there was more than 1 cpu device.
Fix this by only generating them once by removing the
acpi_fill_ssdt_generator for the cpu devices, but add the
generator to the cpu cluster device.
BUG=chrome-os-partner:44084
BRANCH=None
TEST=Built and booted on glados. Noted ACPI entries only generated once.
