Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

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/mfd 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.

On the way do a few whitespace changes to make indention consistent.

With the help of EXPORT_NS_GPL_DEV_PM_OPS() and other *_PM_OPS() macros
we may convert PM ops functions to become static. This also takes into
account the PM configuration options such as CONFIG_PM and CONFIG_PM_SLEEP.
This all removes a lot of ugly macros and ifdeffery in the driver.

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.

Use preferred device_get_match_data() instead of acpi_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Introduce a temporary variable in PCI glue driver to be consistent with
ACPI one on the same matter.

This reverts commit d918e0d5824495a75d00b879118b098fcab36fdb.

The commit in question does not fix anything and only introduces
a duplication in the code. The main intel_lpss_probe() performs
all necessary checks.

While at it and in order of avoiding similar patches to come, add
a comment.

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 ignored (apart
from emitting a warning) 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. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

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

The SPI driver wants to know the exact type of the controller.
Provide this information to it, hence it allows to fix the
Intel Cannon Lake and others in the future.
