[PATCH v2] HID: quirks: Add no_init_reports for AKAI midi controller

[Stafford Horne]

The midi controller times-out while initializing reports, this
causes boot to take an extra 10 seconds. The device descriptor
advertises that it has an internal HID device but seems to not
actually do anything useful.

Resending the same patch for the keyboard to simply disable init reports,
as discussed with Oliver there might be some hidden functionality which
I will look into.  At the moment I dont want to worry about time timeouts. 

Also, I did create and test a patch to use HID_QUIRK_IGNORE which I can 
send if you feel strongly about it. 

Changes in v2
 - use tabs instead of spaces in hid-ids.h
