power: qpnp-typec: report POWER and DATA role for dual role typeC 



Userspace service expects dual_role_instance to report POWER
and DATA role status in order to support role reversal.
Add support to report mode, power and data role.

While at it, enable uevent reporting to userspace for typeC detect
and detach.
