This replaces the previous make-pin-table.py with an implementation based
on boardgen.py.
- MICROPY_PY_MACHINE_PIN_BOARD_CPU macro is removed. This isn't optional
on other ports, so no need for it to be optional on SAMD.
- pin_af_table is removed, and lookups just search the cpu dict instead
(this saves N*wordsize bytes of firmware size to have this extra table).
- pins.csv is now BOARD,CPU to match other ports.

Changes are:
- The pin-af-table-SAMDxx.csv file are moved to the mcu directories with
the name as pin-af-table.csv.
- The handling in Makefile and pin_af.c is simplified.
