pxa2xx_i2c_init() creates a pxa2xx-i2c-slave device on a second i2c-bus,
which has a NULL parent device. This causes an assertion in
object_get_canonical_path() when accessing pxa2xx-i2c-slave's
"parent_bus" link<bus> property in tosa and likely other PXA2xx machines.
Fix this by using the pxa2xx_i2c device, created just before, as parent.
