Subject: [PATCH 30/34] clk: stm32f3: Migrate to clk_hw based OF and registration APIs

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

Cc: Daniel Thompson <daniel.thompson@...aro.org>
Signed-off-by: Stephen Boyd <stephen.boyd@...aro.org>

See commit 58657d189a2f and it's children for details on this
new registration API.
