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.
