[PATCH 1/2] remoteproc: remoteproc_core: Use 'gnu_printf' format notation

[Lee Jones]

Fixes the following W=1 kernel build warning(s):

 drivers/remoteproc/remoteproc_core.c: In function ‘rproc_find_carveout_by_name’:
 drivers/remoteproc/remoteproc_core.c:257:2: warning: function ‘rproc_find_carveout_by_name’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
 257 | vsnprintf(_name, sizeof(_name), name, args);
 | ^~~~~~~~~
 drivers/remoteproc/remoteproc_core.c: In function ‘rproc_mem_entry_init’:
 drivers/remoteproc/remoteproc_core.c:993:2: warning: function ‘rproc_mem_entry_init’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
 993 | vsnprintf(mem->name, sizeof(mem->name), name, args);
 | ^~~~~~~~~
 drivers/remoteproc/remoteproc_core.c: In function ‘rproc_of_resm_mem_entry_init’:
 drivers/remoteproc/remoteproc_core.c:1029:2: warning: function ‘rproc_of_resm_mem_entry_init’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
 1029 | vsnprintf(mem->name, sizeof(mem->name), name, args);
