iio: core: switch info_mask fields to unsigned long to match find_bit helpers
for_each_set_bit()/find_*_bit() expect arrays of unsigned long (see
include/linux/find.h), but industrialio-core passed const long * into
iio_device_add_info_mask_type{,_avail}().
These masks are used purely as bit arrays and are populated via BIT()
(1UL << n). Switch the info_mask_* fields and the corresponding function
parameters to unsigned long so the types match the helpers. This removes
sparse warnings about signedness mismatches (seen with 'make C=1'
CF='-Wsparse-all') without changing behavior or struct layout.
No functional change intended.
