hwmon: (pmbus/ibm-cffps) Fix write bits for LED control

Browse Source 
[ Upstream commit 76b72736f574ec38b3e94603ea5f74b1853f26b0 ]

When doing a PMBus write for the LED control on the IBM Common Form
Factor Power Supplies (ibm-cffps), the DAh command requires that bit 7
be low and bit 6 be high in order to indicate that you are truly
attempting to do a write.
