Subject: [PATCH] mtd: Use of_property_read_bool()

Use of_property_read_bool() to read boolean properties rather than
of_get_property(). This is part of a larger effort to remove callers
of of_get_property() and similar functions. of_get_property() leaks
the DT property data pointer which is a problem for dynamically
allocated nodes which may be freed.
