iio: ad4310: Replace devm_clk_register() with devm_clk_hw_register()

The devm_clk_register() is deprecated and devm_clk_hw_register() should be
used as a replacement.

Switching to the clk_hw interface also allows to use the built-in device
managed version of registering the clock provider. The non-clk_hw interface
does not have a device managed version.
