Input: cypress-sf - register a callback to disable the regulators

When the driver fails to probe, we will get the following splat:

[   19.311970] ------------[ cut here ]------------
[   19.312566] WARNING: CPU: 3 PID: 375 at drivers/regulator/core.c:2257 _regulator_put+0x3ec/0x4e0

Fix this by adding a callback that will deal with the disabling when the
driver fails to probe.
