First thing since "op_mode" is not generic property, I think it should
be appended with some driver specific prefix.

But IMHO its quite generic property used and required by many other
PMICs(almost all used by Samsung).
I would like to use this opportunity to discuss about adding it as
generic regulator constraint(as initial_mode)
by providing a default mapping of generic Regulator operating
modes(kernel specific) to operating modes supported by hardware in
regulator driver itself.
