sparc32: fix sparse warnings in srmmu.c 

Fix following warnings:
srmmu.c:78:5: warning: symbol 'flush_page_for_dma_global' was not declared. Should it be static?
srmmu.c:85:5: warning: symbol 'viking_mxcc_present' was not declared. Should it be static?
srmmu.c:103:6: warning: symbol 'srmmu_nocache_bitmap' was not declared. Should it be static?
srmmu.c:176:24: warning: Using plain integer as NULL pointer
srmmu.c:731:46: warning: Using plain integer as NULL pointer
srmmu.c:731:46: warning: Using plain integer as NULL pointer
srmmu.c:731:46: warning: Using plain integer as NULL pointer
srmmu.c:870:13: warning: symbol 'srmmu_paging_init' was not declared. Should it be static?

Add proper prototypes in mm_32.h and drop local prototype in init_32.c
Replace 0 with NULL
