Hi Andrew,

you are right. Have to remove these lines. Besides enabling the interrupt
in MDIO_MMD_PCS_MV_TEMP_SENSOR1, there are two further register writes
necessary to make the interrupt propagate. I didn't want it to propagate.
Anyway it's wrong. I couldn't find a good solution to use the temperature
interrupt. Will have a look into this, and probably figuring out how to
do so. But it won't be part of this patch series.
