clk: bcm: 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.

clk: bcm: dvp: Add MODULE_DEVICE_TABLE()

Add MODULE_DEVICE_TABLE() so as to be able to use the driver as a
module. More precisely, for the driver to be loaded automatically at
boot.

clk: bcm: dvp: drop a variable that is assigned to only

The third parameter to devm_platform_get_and_ioremap_resource() is used
only to provide the used resource. As this variable isn't used
afterwards, switch to the function devm_platform_ioremap_resource()
which doesn't provide this output parameter.

clk: bcm: dvp: Add missing module informations

The driver for the DVP controller in the BCM2711 was missing the MODULE_*
macros resulting in a modpost warning at compilation.

clk: bcm: Add BCM2711 DVP driver

The HDMI block has a block that controls clocks and reset signals to the
HDMI0 and HDMI1 controllers.

Let's expose that through a clock driver implementing a clock and reset
provider.
