Rainier: Add a presence to bind delay of 1500ms
The firmware code in these power supplies takes about 1500 milliseconds
to boot after they are inserted, and the presence line goes active.
Until the firmware has completely booted, the power supplies will not
respond to the I2C traffic initiated by the BMC device driver code as it
attempts to probe the hardware.
Adding in a DRIVER_BIND_DELAY_MS environment variable, set to 1500
(milliseconds), to delay the device driver binding in order to hold off
the probe until the power supply firmware should be ready, in order to
avoid ENXIO errors.
