boards/dwm1001: add saul_gpio support

[blueted2]

Contribution description

Add saul support for the dwm1001-dev's LEDs and "USER" button.
The pin macros were already present for this board, all that remained was to add the gpio_params.h header and include the saul_gpio pseudomodule in the board's Makefile.dep.

Added LEDs:

• LED0 - Green
• LED1 - Red
• LED2 - Red
• LED3 - Blue

Added button:

• Button 1 - Labelled as "USER"

Testing procedure

Below is the terminal output where each LED has been toggled by shell command, and a before/after of pressing the "USER" button.

I'm not quite sure what you mean, but please squash your commits

[blueted2]

I think I have squashed the commits, although I may have simply caused a mess... Let me know if I should just start a fresh pull-request.

[benpicco]

Huh, all looks good. There is only a single commit and it only touches the two files it needs.

[benpicco]

ah KConfig needs an update too
