This adds a probe quirk to some generic USB mini keyboard, those uses Elan's USB vendor ID and 0x1213 as product ID.

Those keyboards does not report current device state and would fail to initialize under U-Boot with the following error:

"Failed to get keyboard state from device 04f3:1213"

It's not known if those generic USB mini keyboard has the same VID/PID.

Is it all keyboards from this vendor that are affected, or should this quirk be applied only to a specific VID/PID of this device ?
