Upstream DT uses simple-pm-bus instead of simple-bus. simple-pm-bus requires power domain support. On am33xx, PRM manages power domains but all domains are enabled at boot. Add stub driver with custom of_xlate that expects no argumetns to allow simple-pm-bus and dependent devices to probe. Signed-off-by: Markus Schneider-Pargmann (TI.com) <msp@baylibre.com>
