Simon Glass 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.
