mv643xx_eth: Fix compile error for architectures without clk.
Commit 452503ebc (ARM: Orion: Eth: Add clk/clkdev support.) broke the building of the driver on architectures which don't have clk support. In particular PPC32 Pegasos which uses this driver. Add #ifdef around the clk API usage. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
