[PATCH 4/7] spi: pl022: attempt to get sspclk by name

To me it feels odd to require the last clock in the list (apb_pclk) to
be named, and the rest to be in a particular order. For the dt case it
seems saner to add new clocks with names as it allows arbitrary subsets
of clocks to be wired up and described (though obviously in this case a
missing sspclk would be problematic).

Yes, good point about the missing clocks, and I also agree mixing ordered
and named clocks in one device is rather odd and can lead to trouble.

I guess there isn't really a good way out here, and I certainly won't
ask for it to be done one way or the other if someone else has a 
good argument which way it should be implemented.
