[REGRESSION] And a drity fix for 0cf3:3004 QCA Rome device

[Dmitry Tunin]

Hi, Marcel

Since  f44cb4b older AR3012 devices stopped working. We discussed that
before that QCA released a ROME device with a duplicate code.

If there is no easy way to check which one is used, then it may be a
good decision to change the kernel code for the newer device in new
kernels.

But anyway it should be made cleaner. The device is still listed in
ath3k.o as an AR3012.

Regards,

Dmitry.
