Update FPDT length

If FPDT->Length is just the size of FIRMWARE_PERFORMANCE_TABLE,
BOOT_PERFORMANCE_TABLE and S3_PERFORMANCE_TABLE are overwritten
by the next Table in ACPI init. Therefore, make the size in the
header as sizeof(INTERNAL_FIRMWARE_PERFORMANCE_TABLE) so that
the next table starts after INTERNAL_FIRMWARE_PERFORMANCE_TABLE.
Otherwise, S3 Perf Table can't be located on S3 resume path.
