MPC 8240 pvr?

[Tad Hunt <tad%entrisphere.com@localhost>]

Hey.  I'm adding support to NetBSD-1.6.1 for the MPC8260 and MPC8275
(bringing it forward from NetBSD-1.5.0).  Anyway, the MPC 8260 PVR
is 0x0081.  This is apparently the same value at the MPC8240,
according to sys/arch/powerpc/include/spr.h

I don't have access to an MPC8240 to verify that the PVR is correct,
but I know for a fact that it is correct for the MPC8260.  Can
someone verify the MPC8240?  Otherwise, I'm just going to rename
the constant from MPC8240 to MPC8260...

Thanks,
        -Tad
