There is little reason for this if statement to use bitwise ORs, as the
short circuiting of logical OR does not need to be avoided in this
context; it would be wasteful to call device_property_read_bool() three
times if the first two calls returned true. Switch to logical OR to fix
the warning.

While in the area, the parentheses around the calls to
device_property_read_bool() are not necessary and make the if statement
harder to read, so remove them.
