Update tegra234_fuse_keepouts list to allow reading these fuse from
nvmem sysfs interface.

Kernel coding style expects all drivers to ignore debugfs errors.
Partially because it is purely for debugging, not for important user
interfaces.  Simplify the code by dropping unnecessary probe failuring
and error message on debugfs failures, which also fixes incorrect usage
IS_ERR_OR_NULL() and Smatch warning:

  drivers/soc/tegra/cbb/tegra-cbb.c:80 tegra_cbb_err_debugfs_init() warn: passing zero to 'PTR_ERR'

<title>soc: Switch back to struct platform_driver::remove()</title>

<content type='text'>
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/soc 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.

two places to save some boilerplate.

Commit 6f4429e21a7f ("soc/tegra: pmc: Update address mapping sequence
for PMC apertures") updated the resource lookup code in the PMC driver.
Instead of calling platform_get_resource_byname() and
devm_ioremap_resource() simplify the code by simply calling
devm_platform_ioremap_resource_byname().

<title>mm/util: Swap kmemdup_array() arguments</title>

<content type='text'>
GCC 14.1 complains about the argument usage of kmemdup_array():

  drivers/soc/tegra/fuse/fuse-tegra.c:130:65: error: 'kmemdup_array' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
    130 |         fuse-&gt;lookups = kmemdup_array(fuse-&gt;soc-&gt;lookups, sizeof(*fuse-&gt;lookups),
        |                                                                 ^
  drivers/soc/tegra/fuse/fuse-tegra.c:130:65: note: earlier argument should specify number of elements, later size of each element

The annotation introduced by commit 7d78a7773355 ("string: Add
additional __realloc_size() annotations for "dup" helpers") lets the
compiler think that kmemdup_array() follows the same format as calloc(),
with the number of elements preceding the size of one element. So we
could simply swap the arguments to __realloc_size() to get rid of that
warning, but it seems cleaner to instead have kmemdup_array() follow the
same format as krealloc_array(), memdup_array_user(), calloc() etc.
