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.

82d5464788 mmc: jz_mmc: Compile-out write support if disabled
Do not build write support, unless it's enabled.

In the SPL case, this change will typically remove
precious bytes (as write support is most often
not needed in SPL).

This is important on this platform, where the maximum
SPL size is 14 KiB.

With gcc v7.3, this change saves 144 bytes producing:

size spl/u-boot-spl
   text	   data	    bss	    dec	    hex	filename
   9240	    752	    712	  10704	   29d0	spl/u-boot-spl

To make the code easier to compile-out and more
readable, a pair of read_data/write_data helpers are created.
