The dummy declaration for nvmem_cell_write() has a different prototype
from the one that is normally used, and it causes a warning when
CONFIG_NVMEM is disabled:
drivers/power/reset/nvmem-reboot-mode.c:27:42: error: incompatible pointer
types passing 'unsigned int *' to parameter
of type 'const char *' [-Werror,-Wincompatible-pointer-types]
ret = nvmem_cell_write(nvmem_rbm->cell, &magic, sizeof(magic));
Make the second argument a void pointer like the other prototype has.
Fixes: 69aba7948cbe ("nvmem: Add a simple NVMEM framework for consumers")
Fixes: 7a78a7f7695b ("power: reset: nvmem-reboot-mode: use NVMEM as reboot mode
write interface")
