Subject: [PATCH 2/2] hwmon: (pmbus/ibm-cffps) Set the PMBUS_NO_PEC flag

Several power supplies supported by the IBM CFFPS driver don't
report valid data in the CAPABILITY register, or support PEC only
for certain PMBus registers. Since the automatic version detection
of the driver might fail on some supplies with PEC enabled, just
disable PEC entirely for this driver.
