power: qpnp-smb2: Update the SMB2 charger driver 



Update the QPNP SMB2 charger driver for the
msm-3.18 kernel. The following are the updates -

1. Support the legacy SPMI driver design
2. Remove USB psy (implemented in the USB software stack)
3. Add present and charger-type power supply notifications
