psusensor: support ibm cffps driver

certain PSU's, like ACBEL R1CA2122A do not comply with the mechanism
that 'pmbus' driver uses to discover the number of pages.

In that case, the hwmon directory is filled with garbage sensors,
and hardcoding the number of pages is required.

IBM cffps driver hardcodes the number of pages. This commit is to
support using this driver in EM config.

Tested: on Tyan s8030 Board with before mentioned powersupplies.
