Subject: [RFC 0/2] x86: Add support for Atheros AR1520 GPS devices

These two patches adds support for the Atheros AR1520 GPS device,
currently only pegged onto an mrst platform. This creates a character
device called ar1520 and lets userspace talk to it through it. My only
concern against this approach is that it this requires a custom userspace
application for reseting the device, waking it up and for blocking reads
through ioctl. The character device can be used to read/write data to it
as well.

I'll try to get more information and details on the userspace application
and document stuff here:

http://wireless.kernel.org/en/users/Drivers/ar5120

In the meantime some review and testing would be appreciated as I modified
the original code a bit.
