[PATCH] crypto: atmel-ecc - remove stale comments in atmel_ecc_remove

[Thorsten Blum <thorsten.blum@linux.dev>]

atmel_ecc_remove() no longer returns -EBUSY since commit 7df7563b16aa
("crypto: atmel-ecc - Remove duplicated error reporting in .remove()")
and is a void function since commit ed5c2f5fd10d ("i2c: Make remove
callback return void").

Remove and update the outdated comments.
