Use internal.h in a similar way to the internal.h in sam3x8e. Also,
move the twi pin definitions from internal.h to i2c.c (as they are only
used there).

The bank_id was calculated erroneously. Also unify gpio_in_setup and gpio_out_setup a bit. Also disable make flash for the sam4e8e port as it currently references a version of bossac that is not present on all systems.

This can be flashed to e.g. the duet wifi using bossac. It requires a
later version as is currently included in the klipper repo (1.8
vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD
