* usb_device_state: add idle_rate, led and protocol
Previously all usb drivers and platform implementations (expect for our
oddball atsam) tracked the same two global variables:
- keyboard_protocol: to indicate if we are in report or boot protocol
- keyboard_idle: for the idle_rate of the keyboard endpoint
And a local variable that was exposed trough some indirection:
- keyboard_led_state: for the currently set indicator leds (caps lock etc.)
These have all been moved into the usb_device_state struct wich is
accessible by getters and setters.
This reduces code duplication and centralizes the state management
across platforms and drivers.

* usb_device_state: reset protocol on reset
The usb hid specification section 7.2.6 states:
When initialized, all devices default to report protocol. However the
host should not make any assumptions about the device’s state and should
set the desired protocol whenever initializing a device.
Thus on reset we should always do exactly that.

* Allow for `get_hardware_id()` to be used for serial number.
* Length checks.
* Explain length.
* Cleanup.
* Preprocessor magic.
* Use the force, Batman.
* Swap logic; if SERIAL_NUMBER is defined use that, otherwise derive it.
* Cleanup.
* Cleanup.
* ChibiOS: USB HID control request as dedicated struct
Instead of accessing the raw USB setup packet and documenting the values
as the corresponding USB HID control request fields we introduce a
struct that allows direct access to the fields. This is safer and self
documenting.
* Rename usb_request.h to usb_types.h
In the future all shared USB data types can live in this file.
