f042ebcfcc clk: axm5516: Use managed of_clk_add_hw_provider()
Use the managed `devm_of_clk_add_hw_provider()` instead of
`of_clk_add_hw_provider()`.

This makes sure the provider gets automatically removed on unbind and
allows to completely eliminate the drivers `remove()` callback.

1920aa93a8 clk: axm5516: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

2239fe59ac clk: axm5516: Remove usage of CLK_IS_BASIC
This flag doesn't look to be used by any code, just set in various clk
init structures and then never tested again. Remove it from these
drivers as it doesn't provide any benefit.

235d2aaa77 clk: axm5516: 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. Make thing simple by using the
existing clk_hw array and implementing a custom DT clk provider
get function to map the clk spec id to a clk_hw pointer.

c675a00c2d clk: Add clock driver for AXM55xx SoC
Add clk driver to support clock blocks found on the AXM55xx devices. The driver
provides clock implementations for three different types of clock devices on
the AXM55xx device: PLL clock, a clock divider and a clock mux.
