Actually, the omap_device creation will create this kind of alias for
you, with the device name populated etc, so adding device names here
isn't necessary.

For omap_devices where drivers are always using clk_get(dev, ...),
the name in the initial clkdev table here really doesn't matter.

However, for core code that needs to do a clk_get(NULL, "name"), then
this name matters.  In chatting with Paul offline, he mentioned part of
the CCF conversion will be using clk_get(NULL, ...) on the main_clk
listed in each hwmod.  For that reason, it's important that this string
match the name in the hwmod.

I belive the patch below should make this compatible with any future
use.

Jean, can you fold this into $SUBJECT patch?

Thanks,

Kevin
