iio: light: Simple conversions to iio_push_to_buffers_with_ts()

This new function allows for runtime checks on the provided source buffer
being of sufficient size to accommodate the enabled channel data layout and
the naturally aligned s64 timestamp (which is non obvious and a frequent
source of bugs in the past).

This patch includes the remaining simple cases for light sensor drivers.
