docs: arm: convert docs to ReST and rename to *.rst

Converts ARM the text files to ReST, preparing them to be an
architecture book.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

+SPEAr ARM Linux Overview
+========================
+
+Introduction
+------------
+
+  SPEAr (Structured Processor Enhanced Architecture).
+  weblink : http://www.st.com/spear
+
+  The ST Microelectronics SPEAr range of ARM9/CortexA9 System-on-Chip CPUs are
+  supported by the 'spear' platform of ARM Linux. Currently SPEAr1310,
+  SPEAr1340, SPEAr300, SPEAr310, SPEAr320 and SPEAr600 SOCs are supported.
+
+  Hierarchy in SPEAr is as follows:
+
+  SPEAr (Platform)
+	- SPEAr3XX (3XX SOC series, based on ARM9)
+		- SPEAr300 (SOC)
+			- SPEAr300 Evaluation Board
+		- SPEAr310 (SOC)
+			- SPEAr310 Evaluation Board
+		- SPEAr320 (SOC)
+			- SPEAr320 Evaluation Board
+	- SPEAr6XX (6XX SOC series, based on ARM9)
+		- SPEAr600 (SOC)
+			- SPEAr600 Evaluation Board
+	- SPEAr13XX (13XX SOC series, based on ARM CORTEXA9)
+		- SPEAr1310 (SOC)
+			- SPEAr1310 Evaluation Board
+		- SPEAr1340 (SOC)
+			- SPEAr1340 Evaluation Board
+
+Configuration
+-------------
+
+  A generic configuration is provided for each machine, and can be used as the
+  default by::
+
+	make spear13xx_defconfig
+	make spear3xx_defconfig
+	make spear6xx_defconfig
+
+Layout
+------
+
+  The common files for multiple machine families (SPEAr3xx, SPEAr6xx and
+  SPEAr13xx) are located in the platform code contained in arch/arm/plat-spear
+  with headers in plat/.
+
+  Each machine series have a directory with name arch/arm/mach-spear followed by
+  series name. Like mach-spear3xx, mach-spear6xx and mach-spear13xx.
+
+  Common file for machines of spear3xx family is mach-spear3xx/spear3xx.c, for
+  spear6xx is mach-spear6xx/spear6xx.c and for spear13xx family is
+  mach-spear13xx/spear13xx.c. mach-spear* also contain soc/machine specific
+  files, like spear1310.c, spear1340.c spear300.c, spear310.c, spear320.c and
+  spear600.c.  mach-spear* doesn't contains board specific files as they fully
+  support Flattened Device Tree.
