attaching for easy apply,
pasting for easy review.
Ive patched these new constants into 2 places - where theyll be used.
It occurred to me (post fact) that maybe this isnt desirable.
If thats the case, please also indicate if a final fix-up patch is OK,
Id prefer not to have to try to insert a fix at the beginning of the
patchset

Subject: [PATCH] hwmon/pc87360 separate alarm files - define some constants
2 different kinds of constants added:
- CHAN_ALM_* constants for (later) vin, temp alarm callbacks.
- CHAN_* conversion constants, used in _init_device, partly for RW1C bits
