[PATCH-v6 1/6] mfd: 88pm800: remove duplicate dev_err calls during probe

During probe, inside fn device_800_init(), submodule init is
happening and the same error message is getting printed in both
the places, <subdev>_init() and inside device_800_init().

So this patch gets rid of dev_err from <subdev>_init() fns.
