commit 1ad4b5a7de16806afc1aeaf012337e62af04e001 upstream.
The Cypress HX3 hubs use different default PID value depending
on the variant. Update compatibles list.
Becasuse all hub variants use the same driver data, allow the
dt node to have two compatibles: leftmost which matches the HW
exactly, and the second one as fallback.
