pseq: Create PMBusDriverDevice class

Create the PMBusDriverDevice class in the phosphor-power-sequencer
application.

This class is used for power sequencer devices that are bound to a PMBus
device driver.  It obtains PMBus information from sysfs/hwmon files
created by the driver.

Tested:
* Performed all of the following tests on Rainier and Everest systems
* Correct sysfs/hwmon files and directories found
* GPIO values obtained successfully
* STATUS_WORD values obtained successfully
* STATUS_VOUT values obtained successfully
* READ_VOUT values obtained successfully
* VOUT_UV_FAULT_LIMIT values obtained successfully
* Mapping built from PMBus PAGE numbers to hwmon file numbers
* Verified error paths and exceptions thrown
