Subject: [PATCH] Add spi-max-frequency properties to all spigen nodes.  This
 is a required property for spi devices, although in the spigen case it's
 expected that the speed will be overridden at runtime via the ioctl
 interface.  A very conservative 500khz speed is used (I've never seen a spi
 device that couldn't run at 1mhz).
