Yes, that would be much better.  In that case, this patch can be 
replaced with the two below.  I'll repost the series with the other 
patches refreshed, but I'd like someone with AT91 knowledge to check 
that at91_clock_associate() is doing what I think it is first.

This also means that the driver doesn't need a conditional on ARCH_AT91 
for the pclk name.
