i2c: mux: pinctrl: use flexible-array member and struct_size() helper
Update the code to use a flexible array member instead of a pointer in
structure i2c_mux_pinctrl and use the struct_size() helper.
Also, make use of the struct_size() helper instead of an open-coded
version in order to avoid any potential type mistakes, in particular
in the context in which this code is being used.
So, replace the following form:
sizeof(*mux) + num_names * sizeof(*mux->states)
with:
struct_size(mux, states, num_names)
This code was detected with the help of Coccinelle.
