baytrail: fix uninitialized acpi structures

The callers of the following functions assume the storage
    area provided by the pointers is initialized. That's not the
    case as these were just place holders.
    - void acpi_create_intel_hpet(acpi_hpet_t * hpet);
    - void acpi_create_serialio_ssdt(acpi_header_t *ssdt);

To fix this properly initialize the hpet entry, and just remove
    the serialio_ssdt function entirely.

BUG=chrome-os-partner:23505
    BRANCH=None
    TEST=Built and booted through depthcharge on rambi. Noted no more
         ACPI errors relating to invalid length.
