w1-eeprom: ds24xxx: fix data abort in ds24xxx_probe()

Data abort was occurring when using "w1 bus" with a DS24B33 present.

The abort occurred in the ds24xxx_probe() because the struct w1_device
pointer was NULL. This is because that structure  is allocated by
the parent device uclass (by .per_child_platdata_auto_alloc_size)
and thus the correct accessor is dev_get_parent_platdata() not
dev_get_platdata()
