[PATCH 2/4] mtd: rawnand: meson: use of_property_count_elems_of_size helper

[Martin Blumenstingl]

Use the of_property_count_elems_of_size() helper instead of open-coding
it's logic. As a bonus this will now error out if the "reg" property
values use an incorrect size (anything other than sizeof(u32)).
