Staging: iio: Fix up the module build.

Browse Source 
Both the max1363 and lis3l02dq modules rely on IIO trigger support in
their ring buffer implementations, which is presently a separate config
option. In the case of IIO_RING_BUFFER=y and IIO_TRIGGER=n, we end up
with the following:

This adds an IIO_TRIGGER select for these two drivers conditional on
IIO ring buffer support. Caught with an SH randconfig in -next.
