Subject: [PATCH] wifi: ath11k: Use of_property_present() to test property presence

The use of of_property_read_u32() isn't really correct as
"memory-region" contains phandles (though those happen to be u32s. As
it is just testing for property presence, use of_property_present()
instead.

I'm assuming this should still go to linux-wireless list? I had to 
manually add that, so looks like recent MAINTAINERS changes aren't quite 
right.
