Simmel had USB HID disabled in order to save space. However, the board
configuration did not set USB_DEVICES, causing it to inherit the default
device bouquet of MSC,CDC,MIDI,HID. This in turn caused HID to be included
in the USB Configuration Descriptor.
For some reason, this was not a problem in an earlier version of tinyusb or
circuitpython. However, in the most recent version this has rightfully
caused asserts to appear during configuration.
Re-enable USB_HID for now, as it doesn't add too much in terms of space.
We may disable it again later on if we become pressed for space.
