[PATCH 1/3] phy: mvebu-cp110-comphy: fix mux error check

[Antoine Tenart]

The mux value is retrieved from the mvebu_comphy_get_mux() function
which returns an int. In mvebu_comphy_power_on() this int is stored to a
u32 and a check is made to ensure it's not negative. Which is wrong.
This fixes it.
