[PATCH] sim: frv: fix -Wincompatible-function-pointer-types warnings [PR sim/29752]

[Mike Frysinger]

Some compilers warn in the frv code:
sem.c:24343:41: error: incompatible function pointer types passing
  'void (SIM_CPU *, UINT, UDI)' (aka 'void (struct _sim_cpu *, unsigned int, unsigned long)')
  to parameter of type
  'void (*)(SIM_CPU *, UINT, DI)' (aka 'void (*)(struct _sim_cpu *, unsigned int, long)') [-Wincompatible-function-pointer-types]

This is due to frvbf_h_acc40U_set using UDI for setting the new value,
but using the common sim_queue_fn_di_write API which uses DI.  The same
size, but different sign.  We can change frvbf_h_acc40U_set to take a
DI without changing behavior in practice: the UDI is already passed via
the queue function which accepts a DI, and frvbf_h_acc40U_set already
casts the input to UDI before running any operations on it.
