disable_mmu() cannot work as a C function as there is no control
over data accesses generated by the compiler between disabling and
cleaning the data cache. This results in reading stale data from
main memory.

This patch removes the C version of this function in juno code.
An assembly version has been introduced in commit 2f5dcfef.

This is a miscellaneous commit that fixes all build
errors introduced by the rebase of the Juno codebase
on the latest trusted firmware.

 - Make codebase consistent in its use of #include "" syntax
   for user includes and #include <> syntax for system includes.

 - Sort header files alphabetically

 - Use tag names for structure types.
   Replace instances of the former io_handle and io_dev_handle
   types with uintptr_t.

 - Review the .c and .S files for which header files really need
   including and reorder the #include statements alphabetically.

Also remove 'PL011_BASE' macro because it is no longer used.

These changes are necessary because of commit 2bf28e62.

In the Juno port, this function returns the first entry of the
frequency modes table from the memory mapped generic timer.

Workaround for issue #68

 - Distinguish Juno specific from platform agnostic constants
 - Define constants for Juno TZC-400 NSAID

It is easier to have all platform constants in the same place.

As for FVP platforms, Juno provides some LEDs that we can
use to report exceptions during the early boot code.

Juno has a "taped out" BL1.

To run your own BL1 on the board, you have to place it in a "ROM bypass"
address and configure the platform to boot from there.

The agreed bypass address is an offset of 0x03EC0000 from the start of
NOR flash (0x08000000), which equates to 0x0BEC0000.

To run the model using a BL1 in bypass mode, you should use a parameter
set something like this:

	<path to>/FVP_CSS_Juno3 \
		-C css.aon.scp.ROMloader.fname=<SCP ROM filename> \
		--data css.cluster1.cpu0=bl1.bin@0x0BEC0000 \
		-C soc.scc.apps_alt_boot=0x0BEC0000

To build BL1 as a ROM located at address zero, you can over-ride the
default value for TZROM_BASE by passing parameters to make, eg:

	ASFLAGS="-D TZROM_BASE=0x00000000" \
	CFLAGS="-D TZROM_BASE=0x00000000" \
	CROSS_COMPILE=aarch64-linux-gnu- \
	make PLAT=juno DEBUG=1 all

Then you can launch the model using a command such as:

	<path to>/FVP_CSS_Juno3 \
		-C css.aon.scp.ROMloader.fname=<SCP ROM filename> \
		-C css.trustedBootROMloader.fname=<path to>/bl1.bin \

Note, on Juno mailboxes are 16 bytes because any bigger and they would
overlap the memory used for MHU payload data for SCP->AP transfers.

Previously, platform.h contained many declarations and definitions
used for different purposes. This file has been split so that:

* Platform definitions used by common code that must be defined
  by the platform are now in platform_def.h. The exact include
  path is exported through $PLAT_INCLUDES in the platform makefile.

* Platform definitions specific to the FVP platform are now in
  /plat/fvp/fvp_def.h.

* Platform API declarations specific to the FVP platform are now
  in /plat/fvp/fvp_private.h.

* The remaining platform API declarations that must be ported by
  each platform are still in platform.h but this file has been
  moved to /include/plat/common since this can be shared by all
  platforms.
