Use sdhci_pltfm_remove() instead of sdhci_pltfm_unregister() because
sdhci_pltfm_unregister() is going to be removed.

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.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

I noticed below error msg with sdhci-pxav3 on some berlin platforms:
[.....] sdhci-pxav3 f7ab0000.sdhci failed to add host
It is due to getting related vmmc or vqmmc regulator returns
-EPROBE_DEFER. It doesn't matter at all but it's confusing.
>From another side, if driver probing fails and the error number isn't
-EPROBE_DEFER, the core will tell us something as below:
[.....] sdhci-pxav3: probe of f7ab0000.sdhci failed with error -EXX
So it's not necessary to emit error msg if sdhci_add_host() fails. And
some other sdhci host drivers also have this issue, let's fix them
together.

The sdhci_pltfm_data structure is only passed as the second argument
of sdhci_pltfm_init, which is const, while the sdhci_ops structure
is only stored in the ops field of a sdhci_pltfm_data structure,
which is also const. Thus both kinds of structures can be const as
well.

This patchset renames all uses of "bcm," name bindings to
"brcm," as they were done prior to knowing that brcm had
already been standardized as Broadcom vendor prefix
