[PATCH] Fix big-endian USB gadget build 

Initializers must be constant expressions, and thus we can't use the
complex expression "cpu_to_le*()" - the end result of which may have a
constant _value_ but the expression itself isn't a constant expression.

So use the explicitly constant "__constant_cpu_to_*()" expression
instead.
