[PATCH] mfd: cros_ec_dev: Add missing mfd_remove_devices() call in remove

[Enric Balletbo i Serra]

The driver adds different MFD child devices via mfd_add_devices() and
hence it is required to call mfd_remove_devices() to remove MFD child
devices.

Hi Lee,

I saw that you send a mfd-fixes pull request this morning, so sorry in
advance for sending this too late. This was broken since the driver
moved from platform/chrome to mfd (and probably before that), so
it's an old problem. Note that I plan to send a patch series that depends
on this to apply cleanly. If the patch is fine with you and there is any
possibility to go in this version that will be good, if not, let me know
if you prefer queue this in your for-next branch or if you prefer I
include the patch on the series I plan to send on top of it to not mess
things.

Thanks,
 Enric
