[PATCH 4/6] kirkwood: setup clock only in eth helpers.

[Ian Molton]

This patch modifies the ethernet setup helper functions so that they can be
used /purely/ to set up the clocks.

This is part of ongoing work to enable device tree support in the mv643xx.c
ethernet driver, where as yet the kirkwood platform does not have proper clk
support.

This should allow a gradual migration to device tree and later to proper clk
support, wherupon the helper functions can be removed entirely.
