net: phy: simplify phy_get_internal_delay()

Simplify the arguments passed to phy_get_internal_delay() - the "dev"
argument is always &phydev->mdio.dev, and as the phydev is passed in,
there's no need to also pass in the struct device, especially when this
function is the only reason for the caller to have a local "dev"
variable.

Remove the redundant "dev" argument, and update the callers.
