Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.
Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.
This simplifies the code and this is a step towards the goal of deleting
these callbacks.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/media to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

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.

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

In case the IRQ allocation returns an error in dw100_probe(), the pm
runtime is not disabled before to return.
Add the missing unwind goto on the error handling path of the IRQ
allocation request.

The type ops for equal, init and validate have an elems argument,
but this can be taken from struct v4l2_ctrl: ctrl->elems for
equal and init, and ctrl->new_elems for validate (since you are
validating a new control value).
So drop this argument and update all callers.

After a successful call to media_device_init() it is safer to call
media_device_cleanup().
Add the missing call in the error handling path of the probe, as already
done in the remove function.

Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP
core found on i.MX8MP SoC.
The processor core applies a programmable geometrical transformation on
input images to correct distorsion introduced by lenses.
The transformation function is exposed as a grid map with 16x16 pixel
macroblocks indexed using X, Y vertex coordinates.
The dewarping map can be set from application through a dedicated v4l2
control. If not set or invalid, the driver computes an identity map
prior to starting the processing engine.
The driver supports scaling, cropping and pixel format conversion.
