c9dffc9719 w1: replace dt detection by automatic detection
This patch changes the functioning of the detection of w1 devices.
The old way was a comparison between detected w1 and the ones described in
the device tree. Now it will just look for the driver matching the family
id of the w1 detected.

The patch is inspired from Maxime Ripard code.

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.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

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()
