Subject: [PATCH v2 net-next 6/9] net: dsa: felix: attempt to initialize internal hsio plls

The VSC7512 and VSC7514 have internal PLLs that can be used to control
different peripherals. Initialize these high speed I/O (HSIO) PLLs when
they exist, so that dependent peripherals like QSGMII can function.
