arm: Fix ICE on glibc compilation after my DIVMOD optimization [PR97322]
The arm target hook for divmod wasn't prepared to handle constants passed to
the function.

PR target/97322
* config/arm/arm.c (arm_expand_divmod_libfunc): Pass mode instead of
GET_MODE (op0) or GET_MODE (op1) to emit_library_call_value.
* gcc.dg/pr97322.c: New test.
