[PATCH net-next v3 1/2] lan78xx: Enable 125 MHz CLK configuration for LAN7801 if NO EEPROM is detected

[Rengarajan S]

The 125MHz and 25MHz clock configurations are enabled in the initialization
regardless of EEPROM (125MHz is needed for RGMII 1000Mbps operation). After
a lite reset (lan78xx_reset), these contents go back to defaults(all 0, so
no 125MHz or 25MHz clock).
