docs/system: Split target-arm.rst into sub-documents

Currently the documentation for Arm system emulator targets is in a
single target-arm.rst.  This describes only some of the boards and
often in a fairly abbreviated fashion. Restructure it so that each
board has its own documentation file in the docs/system/arm/
subdirectory.

This will hopefully encourage us to write board documentation that
describes the board in detail, rather than a few brief paragraphs
in a single long page. The table of contents should also help users
to find the board they care about faster.

Once the structure is in place we'll be able to move microvm.rst
from the top-level docs/ directory.

All the text from the old page is retained, except for the final
paragraph ("A Linux 2.6 test image is available on the QEMU web site.
More information is available in the QEMU mailing-list archive."),
which is deleted. The git history shows this was originally added
in reference to the integratorcp board (at that time the only
Arm board that was supported), and has subsequently gradually been
further and further separated from the integratorcp documentation
by the insertion of other board documentation sections. It's
extremely out of date and no longer accurate, since AFAICT there
isn't an integratorcp kernel on the website any more; so better
deleted than retained.

+enabled in the kernel, and expect 512M RAM. Kernels for The PBX-A9 board
+should have CONFIG_SPARSEMEM enabled, CONFIG_REALVIEW_HIGH_PHYS_OFFSET
+disabled and expect 1024M RAM.
+
+The following devices are emulated:
+
+-  ARM926E, ARM1136, ARM11MPCore, Cortex-A8 or Cortex-A9 MPCore CPU
