Subject: [PATCH 3/5] regulator: core: Remove unused regulator_*drvdata functions

From: "Dr. David Alan Gilbert" <linux@...blig.org>

regulator_get_init_drvdata() was added in 2008 by the
commit a5766f11cfd3 ("regulator: core - Rework machine API to remove string
based functions.")
regulator_set_drvdata() was also added in 2008 by the
commit 414c70cb91c4 ("regulator: regulator framework core")

neither have been used since,

Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
