ec/google/chromeec: don't put empty block in SSDT

Check that there are actually USB-PD ports for which to
add data to SSDT, before actually generating SSDT data.
This prevents an empty scope from being generated on
devices without any USB-PD ports, which was breaking
parsing/decompilation on some older platforms (eg,
Braswell).

Test: build/boot google/edgar, verify SSDT table able to
be parsed via iasl after dumping.
