power: early register bms_phy client for cw2217_fg

Browse source 
the CW2217 needs 2.5s to biit up when the battery is first buttoned.
During this time, mmi_discrete_probe will delay to waiting get bms_phy.
so get the usb_type type becomes longer. Therefore,
the usb_real_type cannot be obtained immediately after the pr_pd_manage_probe is started.
The mmi_discrete can quickly probe pass if early register bms_phy
and factory test node can created as expect.
