F haptic disable when usb not configured or suspended

[purdeaandrei]

Description

This also add support for specifying a LED pin to indicate haptic status,
and also adds support for a haptic-enable pin, which is useful to turn off
the boost converter on the solenoid driver.

This has been tested on chibios running on an STM32F446.
Also tested on atmega32u4, and also on atmega32u2.

The following pull-request was a pre-requisite: (it's now merged)

Now also tested, and working as expected on atmega32u4, and atmega32u2, in addition to STM32F446.

An interesting observation is that on atmega32u4 the solenoid clicks on a keypress that would bring the system out of suspend. This appears to be because of ordering of events, first USB comes out of the suspend state, and only after is the haptic feedback processed.
If I remember right, when I tested this on STM32F446 the solenoid didn't click when exiting suspend.
These differences are probably related to how the USB drivers are implemented, but I can confirm, that I checked that the solenoid is indeed disabled during suspend, the DC-DC converter is powered down, and I see the output capacitor of the DC-DC converter discharging.

Rebased.
Still awaiting other PR.
Not yet tested after rebase.

[purdeaandrei]

Rebased on top of the latest power tracking PR, and tested again with an STM32F446-based keyboard

[purdeaandrei]

Rebased to fix conflict. Still awaiting other PR.

[purdeaandrei]

Not awaiting any other PR's anymore.
Please remove the awaiting_pr label.
(Also I rebased it again, to fix conflict, and to force github to not show the previous dependency as part of the changes anymore)

[tzarc]

If we can get the conflicts resolved, this should be good to go.

@tzarc Conflict fixed, just needed a rebase
