Add 'if (syspm_pfuze_chip ->chip_id == PFUZE100))' here is easy for
extend Support on pfuze200/3000.. in the feature.

There is already:
static int pfuze_power_off_prepare_init(struct pfuze_chip *pfuze_chip) {
        if (pfuze_chip->chip_id != PFUZE100) {
                dev_warn(pfuze_chip->dev, "Requested
pm_power_off_prepare handler for not supported chip\n");
                return -ENODEV;
        }


No need to add it in pfuze_power_off_prepare()

I saw you add chip check in pfuze_power_off_prepare_init(), but I'm saying
In the future case pfuze200/3000 may should still support this feature, but registers
are different between different chips, thus, move checking chip into pfuze_power_off_prepare()
could make the later patch for pfuze200/3000 more clear, less and easier.
