Match pvsystem.i_from_v, v_from_i single diode parameters with singlediode order.

[reepoi]

Is your feature request related to a problem? Please describe.
The single diode model parameters for i_from_v, v_from_i in pvsystem are expected in a different order than pvsystem.singlediode.
This makes it difficult to pass the parameters to all of these functions using *args.

Describe the solution you'd like
Group and reorder the single diode parameters of i_from_v, v_from_i to match the order of singlediode.
