device property: Add helpers to count items in an array
The usual pattern to allocate the necessary space for an array of properties is
to count them first by calling:
count = device_property_read_uXX_array(dev, propname, NULL, 0);
if (count < 0)
return count;
Introduce helpers device_property_count_uXX() to count items by supplying hard
coded last two parameters to device_property_readXX_array().
