Move SDA/SCL pins into pins.h for fastio compatibility

Browse Source 
fastio relies on macros for pin definitions, so we cannot use the const
declaration in Sd2PinMap or the arduino's definition.

Declare SDA/SCL_PIN into pins.h based on the current MCU, which is
identical in all our variants.

Remove the conflicting/unused declaration in Sd2PinMap.
