[PATCH] mtd: Use of_property_read_bool() for boolean properties

[Rob Herring <robh@kernel.org>]

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to to of_property_read_bool().
