net: bgmac: enable master mode for BCM54210E and B50212E PHYs
There are 4 very similar PHYs: 0x600d84a1: BCM54210E (rev B0) 0x600d84a2: BCM54210E (rev B1) 0x600d84a5: B50212E (rev B0) 0x600d84a6: B50212E (rev B1) that need setting master mode manually. It's because they run in slave mode by default with Automatic Slave/Master configuration disabled which can lead to unreliable connection with massive ping loss. So far it was reported for a board with BCM47189 SoC and B50212E B1 PHY connected to the bgmac supported ethernet device. Telling PHY driver to setup PHY properly solves this issue.
