of: implement of_property_write_strings for multiple strings
The current way to set a property with multiple values (e.g. compatible
strings) is to have
char properties[] = "st,stm32mp157c-dk2\0st,stm32mp157";
of_set_property(np, "compatible", properties, sizeof(properties), 1);
Add a new helper to make this easier at the cost of one runtime
reallocation:
of_property_write_strings(np, "compatible,
"st,stm32mp157c-dk2", "st,stm32mp157", NULL);
