ce1c5f840f clk: xilinx: 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.

b46d59cb18 clk: xilinx: Drop if block with always false condition 
xvcu_remove() is only called for a device after after xvcu_probe()
completed successfully. In that case dev_set_drvdata() was called for
that device with a non-NULL parameter, so platform_get_drvdata() won't
return NULL and the if condition is never true.

Drop the if, preparing a conversion to make platform driver's remove
callback return void.

595c88cda6 clocking-wizard: Support higher frequency accuracy 
Change the multipliers and divisors to support a higher
frequency accuracy if there is only one output.
Currently only O is changed now we are changing M, D and O.
For multiple output case the earlier behavior is retained.

2875a2f3f1 clk: xilinx: Drop duplicate depends on COMMON_CLK 
This entire Kconfig file is only included within the if COMMON_CLK
section of the drivers/clk/Kconfig file. That makes the depends on
COMMON_CLK here redundant. Remove it.

c00b5f2040 clk: clocking-wizard: Depend on HAS_IOMEM 
This driver uses devm_platform_ioremap_resource() and thus depends on
HAS_IOMEM. Add the Kconfig dependency to avoid build issues.

a2fe7baa27 clk: xilinx: move xlnx_vcu clock driver from soc 
The xlnx_vcu driver is actually a clock controller driver which provides
clocks that can be used by a driver for the encoder/decoder units. There
is no reason to keep this driver in soc. Move the driver to clk.

NOTE: The register mapping actually contains registers for AXI
performance monitoring, but these are not used by the driver.
