  1. ev11l78a: minimize memory usage in the default config. 

    The ATSAMD20E16 used in this board only has 8KiB SRAM, so the defaults
are not really suitable for anything close to useful, particularly the
sink sample that most closely resembles the original demo for the board.

This should also allow more tests not to be skipped for this board as
otherwise they overflow RAM usage.

  2. ev11l78a: configure DAC peripheral 

    This configures the DAC in the same way as it is configured for the
arduino_zero and other similar boards.

It also includes the board in the DAC tests.

  3. ev11l78a: add en_sink as a custom binding. 

    This exposes the EN_SINK signal as a custom binding, since it is ore to
the business logic of the board.

EN_SINK is a GPIO line connected to a MOSFET that provides power on the
screw terminal of the board, and should be enabled after USB-PD
negotiation.
