power: reset: sc27xx: Add platform_device_id table
Make the poweroff driver for SC27xx-series PMICs probe automatically.
Since the device representing the poweroff functionality of the SC27xx
PMIC is not supposed to have a dedicated device tree node without any
corresponding DT resources [1], an of_device_id table cannot be used
here. Instead, use a platform_device_id table to match the poweroff
sub-device instantiated by the parent MFD driver.
