driver core: Correct API device_for_each_child_reverse_from() prototype

For API device_for_each_child_reverse_from(..., const void *data,
		int (*fn)(struct device *dev, const void *data))

- Type of @data is const pointer, and means caller's data @*data is not
  allowed to be modified, but that usually is not proper for such non
  finding device iterating API.

- Types for both @data and @fn are not consistent with all other
  for_each device iterating APIs device_for_each_child(_reverse)(),
  bus_for_each_dev() and (driver|class)_for_each_device().

Correct its prototype by removing const from parameter types, then adapt
for various existing usages.

An dedicated typedef device_iter_t will be introduced as @fn() type for
various for_each device interating APIs later.
