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()
