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.
