[PATCH 2/8] macb: detect hclk presence from platform data

Rather than detecting whether we need to do a clk_get() and enable on
the "hclk" based on the kernel configuration, add an extra field to the
platform data.  This makes it cleaner to add more supported
architectures without lots of ifdeffery.

This requires that all instantiations of the device have platform data
defined but that is the case currently anyway.
