iio: Add broken out info_mask fields for shared_by_type and separate
This simplifies the code, removes an extensive layer of 'helper' macros and gives us twice as much room to play with in these masks before we have any need to be clever. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Lars-Peter Clausen <lars@metafoo.de>
