power: smb349: add support for smb349 charger chip
The SMB349 charger chip allows charge batteries
with a higher current. Add this driver to be able to
control charging from kernel space and deliver charging
information to userspace.
Also add debugfs entries to show current register
settings of SMB349 charger.
