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.

a2e99a71b2 w1: Add driver for i.MX bus master controller 
Two variants of controllers are supported:
V1 (bitwise only) found in
	i.MX21, i.MX27, i.MX31, i.MX51
V2 (byte operations) found in
	i.MX25, i.MX35, i.MX50, i.MX53

Only tested on i.MX53 hardware but in both modes
(by modifying the device tree).
