i2c: designware_i2c: Check if the device is powered
If the device doesn't return a version that means the device is non-functional. The dw_i2c_regs had invalid offsets for the version field. I got the correct value from the DesignWare databook. It also matches what the Picasso PPR says. Signed-off-by:Raul E Rangel <rrangel@chromium.org> Reviewed-by:
