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

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

[Rob Herring]

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().

You are using of_property_present() rather than of_property_read_bool()
but I'm not picky about commit message details.

ugg, well, it's the commit message that's correct. I missed updating
this one to use of_property_read_bool().
