The sysfs core now provides callback variants that explicitly take a
const pointer. Use them so the non-const variants can be removed.

Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>

Changes in v2:
- Drop already applied patches
- Drop unnecessary write_new = NULL assignment
- Clarify commit message a bit
- Link to v1: https://lore.kernel.org/r/20241216-sysfs-const-bin_attr-net-v1-0-ec460b91f274@weissschuh.net
