dm: treewide: Rename auto_alloc_size members to be shorter

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

 struct eth_ape_priv contains runtime per-instance data, like buffers, pointers
 to current descriptors, current speed settings, pointers to PHY related data
-(like struct mii_dev) and so on. Declaring its size in .priv_auto_alloc_size
+(like struct mii_dev) and so on. Declaring its size in .priv_auto
 will let the driver framework allocate it at the right time.
 It can be retrieved using a dev_get_priv(dev) call.
