hikey960: set isp clks as unsecure mode

Set alignment size to 512B for Hikey/Hikey960

SPM: Allow secondary CPUs to use the Secure Partition

The Secure Partition should be able to be used from any CPU, not just
the lead one. This patch point the secure contexts of all secondary
CPUs to the same one used by the lead CPU for the Secure Partition. This
way, they can also use it.

In order to prevent more than one CPU from using the Secure Partition at
the same time, a lock has been added.

Whether a Secure Partition is being initialized or not is something
related to that specific partition, so it should be saved with the
rest of the information related to it.

ARM TF has been tested as part of its CI system with the following
dependencies updated:

- Linaro binaries:    17.04 --> 17.10
- mbed TLS library:   2.4.2 --> 2.6.0

The version of AEM, Cortex-A and Foundation models that ARM TF is
tested on has also been updated:

- v11.1 build 11.1:22 --> v11.2 build 11.2:33
- v8.9 build 0.8:8805 --> v9.0 build 0.8:9005

This patch updates the user guide documentation to reflect these
changes to the dependencies.

Additionally, links to Linaro resources have been updated.

Commit 6f625747

 ("Convert documentation to reStructuredText")
automatically converted all documents by a tool.  I see some parts
were converted in an ugly way (or, at least, it is not my intention).
Also, the footnote is apparently broken.

I checked this document by my eyes, and reformated it so that it looks
nicer both in plain text and reST form.

io: block: fix block_read/write may read/write overlap buffer

SPM: Fix MM_COMMUNICATE_AARCH32/64 parameters

With this patch, ARM platforms are expected to define the macros
PLAT_ARM_SDEI_PRIVATE_EVENTS and PLAT_ARM_SDEI_SHARED_EVENTS as a list
of private and shared events, respectively. This allows for individual
platforms to define their own events.

ARM TF does not work correctly if built with a version of gcc
that is configured to use PIE by default (e.g. Debian Stretch).

This patch identifies when such a version of gcc is being used
(by searching for --enable-default-pie) and adds -fno-PIE option
to TF_CFLAGS.

Makefile: Add ability to build dtb (v2)

The block operations were trying to optimize the number of memory
copies, and it tried to use directly the buffer supplied by the user
to them. This was a mistake because it created too many corner cases:

	1- It was possible to generate unaligned
	   operations to unaligned buffers. Drivers that were using
	   DMA transfer failed in that case.

	2- It was possible to generate read operations
	   with sizes that weren't a multiple of the block size. Some
	   low level drivers assumed that condition and they calculated
	   the number of blocks dividing the number of bytes by the
	   size of the block, without considering the remaining bytes.

	3- The block_* operations didn't control the
	   number of bytes actually copied to memory, because the
	   low level drivers were writing directly to the user buffer.

This patch rewrite block_read and block_write to use always the device
buffer, which the platform ensures that has the correct aligment and
the correct size.

This partially reverts commit d6b532b5

, keeping only the fixes to
the assertions. The changes related to the order of arguments passed
to the secure partition were not correct and violated the
specification of the SP_EVENT_COMPLETE SMC.

This patch also improves the MM_COMMUNICATE argument validation.  The
cookie argument, as it comes from normal world, can't be trusted and thus
needs to always be validated at run time rather than using an assertion.

Also validate the communication buffer address and return
INVALID_PARAMETER if it is zero, as per the MM specification.

Fix a few typos in comments and use the "secure partition" terminology
rather than "secure payload".
