[PATCH] ATA: sata_mv: Remove uneeded CONFIG_HAVE_CLK ifdefs

[Ezequiel Garcia]

If CONFIG_HAVE_CLK is not selected, then all the clk API turn out
into stubs, so there's no need to have the ifdefs.
The only side-effect of this patch is the extra tiny kmalloc,
but that's not enough reason to have such ugly ifdefs all around
the code.
