iio: refactor info mask and ext_info attribute creation.
Introduce an enum to specify whether the attribute is separate or
shared.
Factor out the bitmap handling for loop into a separate function.
Tidy up error handling and add a NULL assignment to squish a false
positive warning from GCC.
Change ext_info shared type from boolean to enum and update in all
drivers.
