driver/xf86-input-keyboard wants IDevPtr

[Pat Kane]

I am getting errors while trying to build git master input drivers because
some of them have lines like this:

    static InputInfoPtr KbdPreInit(InputDriverPtr drv, IDevPtr dev, int flags);
   ./xf86-input-keyboard/src/kbd.c:KbdPreInit(InputDriverPtr drv,
IDevPtr dev, int flags)

Looks like  IDevPtr was removed from xfree86/common/xf86str.h

    xfree86: remove IDevRec, replace with InputInfoRec.

    This struct is superfluous, maintaining the same info as the InputInfoRec
    (with the exception of the driver name).

    This is a rather large commit with the majority of changes being a rename
    from the fields of the IDevRec (idev, commonOptions) to the InputInfoRec
    (pInfo, options).

    The actual changes affect the initialization process of the input device:
    In NewInputDeviceRequest, the InputInfoRec is now always allocated and just
    added to the internal list in xf86NewInputDevice() if the init process
    succeeded.
