caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

586d4b010e 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()
