pinmux: stm32f4: Clean-up pinmux arrays
Clean-up the pinmux arrays as a preparatory work before adding more pinmuxes. This is achieved by the following two actions: - Define the PAD macro to simplify the [x - 1] = y construct - Reorder the declartions by bank / pin to make it easier to locate a pin among a high number of other pins, while minimizing the risk of conflict when two people add a new declaration for two different pins Change-Id: I1ca0cc4f48bcd8cfd35b331e9821935f5c855876 Signed-off-by: Florian Vaussard <florian.vaussard@heig-vd.ch>
