sfc: QT202x: Reset before reading PHY id

Browse source

Reading standard registers on the QT2025C before its firmware has
booted may cause the boot process to fail.  Therefore, follow the
recommended reset sequence before reading its id registers.  Either
order works for the QT2022C2, so don't differentiate.
