/* intc_priority(): Configure the level of interrupts

   This function changes the interrupt level of the requested interrupt. Make
   sure you are aware of interrupt assignments to avoid breaking other code.
   This function is mainly used by drivers to enable the interrupts that they
   support.

   The interrupt level should be in the range 0 (disabled) .. 15 (highest
   priority). On SH7305, if the level is not 0, this function also clears the
   associated interrupt mask.

   @intname  Name of the targeted interrupt, from the enumeration above
   @level    Requested interrupt level
   Returns the interrupt level that was assigned before the call. */
