Revert "dt: add documentation of ARM dt boot interface"

This reverts commit 9830fcd6f6a4781d8b46d2b35c13b39f30915c63.

The ARM dt support has not been merged yet; this documentation update
was premature.

-2) Entry point for arch/arm
----------------------------
-
-   There is one single entry point to the kernel, at the start
-   of the kernel image. That entry point supports two calling
-   conventions.  A summary of the interface is described here.  A full
-   description of the boot requirements is documented in
-   Documentation/arm/Booting
-
-        a) ATAGS interface.  Minimal information is passed from firmware
-        to the kernel with a tagged list of predefined parameters.
-
-                r0 : 0
-
-                r1 : Machine type number
-
-                r2 : Physical address of tagged list in system RAM
-
-        b) Entry with a flattened device-tree block.  Firmware loads the
-        physical address of the flattened device tree block (dtb) into r2,
-        r1 is not used, but it is considered good practise to use a valid
-        machine number as described in Documentation/arm/Booting.
-
-                r0 : 0
-
-                r1 : Valid machine type number.  When using a device tree,
-                a single machine type number will often be assigned to
-                represent a class or family of SoCs.
-
-                r2 : physical pointer to the device-tree block
-                (defined in chapter II) in RAM.  Device tree can be located
-                anywhere in system RAM, but it should be aligned on a 32 bit
-                boundary.
-
-   The kernel will differentiate between ATAGS and device tree booting by
-   reading the memory pointed to by r1 and looking for either the flattened
-   device tree block magic value (0xd00dfeed) or the ATAG_CORE value at
-   offset 0x4 from r2 (0x54410001).
