ARM: mach-shmobile: add fixed voltage regulators to kzm9g
On kzm9g provide 1.8V and 2.8V supplies for its SD/MMC-card interfaces and a dummy regulator for the smsc911x driver. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
