xtensa/simdisk: Avoid referring to module::args

When simdisk support is built as a loadable module,
simdisk_param_set_filename() receives a pointer into module::args and
stores each filename pointer as is.

In preparation for removing module::args, update the simdisk.filename
parameter code to copy the provided string. This is somewhat complicated by
the fact that simdisk support can also be built-in, in which case the
parameters are parsed during early boot before slab is available. In that
case, the command line itself is preserved for the lifetime of the kernel,
so continue storing the incoming pointer directly.
