Subject: [PATCH v16 35/42] i2c: rename wait_for_completion callback to wait_for_completion_cb

Functionally no change.  This patch is a preparation for DEPT(DEPendency
Tracker) to track dependencies related to a scheduler API,
wait_for_completion().

Unfortunately, struct i2c_algo_pca_data has a callback member named
wait_for_completion, that is the same as the scheduler API, which makes
it hard to change the scheduler API to a macro form because of the
ambiguity.

Add a postfix _cb to the callback member to remove the ambiguity.
