[PATCH] clk: at91: fix possible dead lock in new drivers

> syscon_node_to_regmap() will make the created regmap get and enable the
> first clock it can parse from the device tree. This clock is not needed to
> access the registers and should not be enabled at that time.
> 
> Use device_node_to_regmap to resolve this as it looks up the regmap in
> the same list but doesn't care about the clocks. This issue is detected
> by lockdep when booting the sama5d3 with a device tree containing the
> new clk bindings.
> 
> This fix already happened in 6956eb33abb5 ("clk: at91: fix possible
> deadlock") for the drivers that had been migrated to the new clk binding
> back then. This does the same for the new drivers as well.
