Raul E Rangel f6f9a01689 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.
