From: Ming Yu <a0282524688@gmail.com>
Move NCT6694_XXX_MOD macro definitions from individual sub-device
drivers into the shared header include/linux/mfd/nct6694.h.
This is a prerequisite for supporting multiple transport interfaces
(USB, HIF) without duplicating these definitions.
No functional change.

Changes in v6:
Changes in v5:
- Split from the monolithic v4 patch to follow the single logical change
principle.
