Use common of_clk_init() function for clocks initialization.

Stephen, if T114 clock series is not going to make in 3.10 then I would
like Mike to take this patch. If T114 clock series makes it then I have
to rebase this patch on top of it.

I'm still just hopeful that it the Tegra114 support can get into 3.10;
all I'm waiting on is Mike's ack to apply it. Let's hold off on this
patch until after that. Thanks.

Prashant, can you please resend this to Mike for inclusion in 3.11; now
that we have moved the Tegra clock driver out of arch/arm/mach-tegra, we
should send all clock driver changes through Mike if possible. Thanks.

Just one question though:

Is clk-provider.h the right header? This code isn't a clock provider?
