Remove the macro PM8001_READ_VPD used to define if a controller WWN should be retrieved from the device. Instead, define the better named boolean module parameter "read_wwn" to control this. The code to set a fixed address for a phy device address when read_wwn is set to false is simplified and fixed to avoid sparse warnings.
