net: phy: Add helper for mapping RGMII link speed to clock rate
The RGMII interface supports three data rates: 10/100 Mbps
and 1 Gbps. These speeds correspond to clock frequencies
of 2.5/25 MHz and 125 MHz, respectively.
Many Ethernet drivers, including glues in stmmac, follow
a similar pattern of converting RGMII speed to clock frequency.
To simplify code, define the helper rgmii_clock(speed)
to convert connection speed to clock frequency.
