iio: dummy: scan index enum update and clean up

This patchset obsoletes the prior single patch:
[PATCH] staging: iio: dummy: clean up the define and usage of dummy_scan_elements

It is split into 3 patches that
1) udpate the existing enum list
2) add timestamp to the enum list
3) cleans one block comment checkpatch err

Changes (other than splitting) since it was a single patch:
- prefaced index names with DUMMY_ to be more descriptive
- fit that block comment on one line by following model of preceeding comment
- did not touch /** comments as they are used for extracting docs

Alison Schofield (3):
staging: iio: dummy: use uppercase descriptors for enum names
staging: iio: dummy: add the timestamp buffer to the scan index enum
staging: iio: dummy: replace block comment with single line comment
