configs/olimex-lpc1766stk: Add support to initialize a USB HID keyboard. Still don't have a working configuration. Seems to require a lot of transfer descriptors. Also reorganized some logic. It has been a long time since the Olimex LPC1766-STK has had any TLC.

*
* Description:
* This function is called by board-bringup logic to configure the HID
* mouse device. This function will register the driver as /dev/inputN
* where N is the minor device number.
*
* Input Parameters:
* minor - The mouse device minor number
*
* Returned Value:
* Zero is returned on success. Otherwise, a negated errno value is
* returned to indicate the nature of the failure.
