Bhupesh Sharma 4220504767 net/phy: realtek: Fix the PHY ID mask to ensure the correct Realtek PHY is detected 
The 'get_phy_driver' code in 'drivers/net/phy/phy.c' uses the following
method to determine which driver is to be loaded for a particular PHY
module:

list_for_each(entry, &phy_drivers) {
	drv = list_entry(entry, struct phy_driver, list);
	if ((drv->uid & drv->mask) == (phy_id & drv->mask))
		return drv;
}

This means that a drv->mask of 0xfffff0 will return incorrect phy driver
for the logic above, even if the drv->uid is anything other than
something ending with a 0x0.

For e.g. if the RTL8211E drv->uid is 0x1cc915 and drv->mask is 0xffffff
and the RTL8211B drv->uid is 0x1cc910 and drv->mask is 0xffffff0, then
the phy driver selected will always be RTL8211B even though the
underlying phy connected on the board is a 8211E module.

This patch fixes this issue.
