gblues 5b37ced196 Update HID pad driver architecture 
== DETAILS

The current HID implementation assumes a very low-level USB library
is being used. This causes a problem on Wii U, because the Cafe OS
only exposes a high-level interface.

To get these functions exposed to the HID pad drivers, I had to make
three changes:

1. I added the legacy "send_control" function to the HID driver
   interface
2. I modified the signature of pad_connection_pad_init() to send the
   driver pointer instead of the function pointer
3. I updated the HID pad drivers to keep the pointer to the driver
   instead of the function pointer, and updated the calls into the
   send_control function as appropriate
4. I updated the HID drivers to use the new pad init signature

== TESTING
Untested, in theory it should work without a hitch because at this
point all I've done is abstract things a little. I still need to
update the HID pad drivers to use the Wii U-specific calls as
appropriate.
