There are several #ifdefs checking for ISP version there. Some
of them are just two different ways to represent the same contants,
while 3 parameters are actually different, depending on the ISP
version.

Change the header in a way that it will be compatible with both
versions, and change dependent code to keep running, removing
ifdefs there only when possible.

There are two ioctls that are only available with ISP2401. Yet,
at the compat level, we don't really need to take care, as
the native ioctl handler will already return an error code if
the ioctl doesn't exist.

So, let's just remove the ifdefs here.

There's a dependency on this header for the ISP model. While

The atomisp supports two different chipsets: ISP2400 and ISP2401.
Right now, this is controlled by ugly #defines inside the driver.

Add a global bolean to identify the type of hardware. While this
is hacky, it would be a quick way to start removing the ugly
ifdefs.
