iio: core: add an accessor for scan_timestamp
indio_dev->scan_timestamp is __private, so a driver has no way to ask
whether the timestamp channel is in the current scan. Hide the
ACCESS_PRIVATE() behind a read-only helper, the way iio_get_masklength()
already does.
The dps310 FIFO patch later in this series is the first user: that
hardware does not timestamp entries, so it refuses a buffer with the
timestamp channel enabled.
