ichspi: Add support for discrete Cannon Lake PCHs

Only minor differences in the Firmware Descriptor, compared to their
predecessors.

We extend our check on the `ICCRIBA` field in the descriptor to dis-
tinguish it from older generation. Alas, the `freq_read` field was
repurposed, so we can't use it as sanity check any more.
