ifdtool: Update to support Skylake+ descriptor format

The descriptor format has changed with Skylake and some fields have
    moved or been expanded.

This includes new SPI frequencies and chip densities, though unfortunately
    30MHz in the new format conflicts with 50MHz in the old format...

There are also new regions with a few reserved regions inserted before
    a new embedded controller region.

Unfortunately there does not seem to be a documented version field
    so there does not seem to be an official way to determine if a
    specific descriptor is new or old.  To work around this ifdtool
    checks the hardcoded "SPI Read Frequency" to see if it set for
    20MHz (old descriptor) or 17MHz (new descriptor).
