[PATCH V2 12/20] mfd: rk808: Use devm_mfd_add_devices() for mfd_device registration

[Laxman Dewangan <ldewangan@nvidia.com>]

Use devm_mfd_add_devices() for MFD devices registration and remove
the call of mfd_remove_devices() from .remove callback to remove
MFD child-devices. This is done by managed device framework.
