Add the ability to disable the USB startup check for Chibios

Browse Source 
- Added support for NO_USB_STARTUP_CHECK. This allows the keyboard do function and not get stuck in a SUSPENDED state loop in case of no USB connection.
- Added support for WAIT_FOR_USB. In LUFA no keyboard has this flag enable therefor no keyboard waits for usb to be active.
- Added documentation for both configuration flags as they were missing.

* Forces the keyboard to wait for a USB connection to be established before it starts up
* `NO_USB_STARTUP_CHECK`
* Disables usb suspend check after keyboard startup. Usually the keyboard waits for the host to wake it up before any tasks are performed. This is useful for split keyboards as one half will not get a wakeup call but must send commands to the master.
