Subject: HID: Renamed fields in HIDDescriptorListNode and HID_Descriptor

In particular HIDDescriptorListNode.cb has been renamed to
HIDDescriptorListNode.descriptor because it contains decriptor data
and not callbacks.

Moreover the HID_Descriptor.descriptor field has been renamed
to HID_Descriptor.data so the structure has now two fields length
and data.

   typedef struct __attribute__((packed)) {
     uint16_t length;
     const void* data;
   } HID_Descriptor;

   class HIDDescriptorListNode {
   public:
     HIDDescriptorListNode *next = NULL;
     const HID_Descriptor *descriptor;
     HIDDescriptorListNode(const HID_Descriptor *d) : descriptor(d) { }
   };

This imply a change in the use of the node from:

  node->cb->lenght
  node->cd->descriptor

to

  node->descriptor->length
  node->descriptor->data

Subject: HID: merged HID_Descriptor into HIDDescriptorListNode

This simplifies the object model and produce a small gain in code
size and performance.
