net: phy: Fix mask value write on gmii2rgmii converter speed register
[ Upstream commit f2654a4781318dc7ab8d6cde66f1fa39eab980a9 ]
To clear Speed Selection in MDIO control register(0x10),
ie, clear bits 6 and 13 to zero while keeping other bits same.
Before AND operation,The Mask value has to be perform with bitwise NOT
operation (ie, ~ operator)
This patch clears current speed selection before writing the
new speed settings to gmii2rgmii converter
