Subject: nvmem: Declare nvmem_cell_read() consistently

From: Guenter Roeck <linux@roeck-us.net>

commit a6c50912508d80164a5e607993b617be85a46d73 upstream.

nvmem_cell_read() is declared as void * if CONFIG_NVMEM is enabled, and
as char * otherwise. This can result in a build warning if CONFIG_NVMEM
is not enabled and a caller asigns the result to a type other than char *
without using a typecast. Use a consistent declaration to avoid the
problem.
