net: phy: sfp: hwmon: Fix scaling of RX power
The RX power read from the SFP uses units of 0.1uW. This must be
scaled to units of uW for HWMON. This requires a divide by 10, not the
current 100.
With this change in place, sensors(1) and ethtool -m agree:
sff2-isa-0000
Adapter: ISA adapter
in0: +3.23 V
temp1: +33.1 C
power1: 270.00 uW
power2: 200.00 uW
curr1: +0.01 A
Laser output power : 0.2743 mW / -5.62 dBm
Receiver signal average optical power : 0.2014 mW / -6.96 dBm
