Andrew Lunn a33710bdb6 net: phy: sfp: Handle unimplemented hwmon limits and alarms ...

Not all SFPs implement the registers containing sensor limits and
alarms. Luckily, there is a bit indicating if they are implemented or
not. Add checking for this bit, when deciding if the hwmon attributes
should be visible.
