Introduced CONFIG_IIO_CHAN_TYPE_GASRESISTANCE

Previous commit 354e27dd introduced a dependency upon IIO_GASRESISTANCE being defined as a member of enum iio_chan_type. The enum is part of the kernel headers and not part of the out-of-tree IIO code in the mangOH repository. The code now checks that CONFIG_IIO_CHAN_TYPE_GASRESISTANCE is defined before trying to reference IIO_GASRESISTANCE.
