sparc: Unbreak the build
Fix the following build errors:
arch/sparc/mm/srmmu.c: In function ‘smp_flush_page_for_dma’:
arch/sparc/mm/srmmu.c:1639:13: error: cast between incompatible function types from ‘void (*)(long unsigned int)’ to ‘void (*)(long unsigned int, long unsigned int, long unsigned int, long unsigned int, long unsigned int)’ [-Werror=cast-function-type]
1639 | xc1((smpfunc_t) local_ops->page_for_dma, page);
| ^
arch/sparc/mm/srmmu.c: In function ‘smp_flush_cache_mm’:
arch/sparc/mm/srmmu.c:1662:29: error: cast between incompatible function types from ‘void (*)(struct mm_struct *)’ to ‘void (*)(long unsigned int, long unsigned int, long unsigned int, long unsigned int, long unsigned int)’ [-Werror=cast-function-type]
1662 | xc1((smpfunc_t) local_ops->cache_mm, (unsigned long) mm);

[ ... ]
Compile-tested only.
