power: qpnp-smbcharger: set DP_DM before PRESENT and TYPE at bootup

It is expected that at charger insertion, DP_DM property be set prior
to setting the usb power supply's PRESENT and TYPE property and at
charger removal DP_DM property be set subsequent to setting the usb power
supply's PRESENT and TYPE property.

At the time of boot up, if a charger is found present the driver only sets
the PRESENT and TYPE property without setting DP_DM property. Fix this.
