[PATCH 4/5] spmi: hisi-spmi-controller: Use devm_spmi_controller_add()

[Fei Shao]

Convert to the device-managed version of spmi_controller_add() and
delete the unnecessary driver remove callback.

Signed-off-by: Fei Shao <fshao@xxxxxxxxxxxx>

Note that I skipped the conversions in spmi-mtk-pmif.c and
spmi-pmic-arb.c because the driver remove sequence would have been
changed, as using the devm version will postpone
spmi_controller_remove() to where after remove callback is executed.
So it turns out only hisi-spmi-controller.c is updated.
