mtd: rawnand: Fix probe failure due to of_get_nand_secure_regions()
Due to 14f97f0b8e2b, the rawnand platforms without "secure-regions"
property defined in DT fails to probe. The issue is,
of_get_nand_secure_regions() errors out if
of_property_count_elems_of_size() returns a negative error code.
If the "secure-regions" property is not present in DT, then also we'll
get -EINVAL from of_property_count_elems_of_size() but it should not
be treated as an error for platforms not declaring "secure-regions"
in DT.
So fix this behaviour by checking for the existence of that property in
DT and return 0 if it is not present.
Fixes: 14f97f0b8e2b ("mtd: rawnand: Add a check in of_get_nand_secure_regions()")
