hwmon: (pmbus/lm25066) Ignore byte writes to non-zero pages
pmbus_clear_faults() attempts to clear faults on non-existing real pages. As a result, the command error bit in the status register is set, and faults are not really cleared. All byte writes to non-zero pages are requests to clear the status register on that page. Since non-zero pages are virtual and do not exist on the chip, there is nothing to do, and such requests have to be ignored. This fixes above problem.
