Juno: Enable non-secure accesses to the system timer ...

This patch programs the CNTCTLBase.CNTNSAR to give non-secure access
to timer frame 1. It also programs the CNTCTLBase.CNTACR1 to give
access to all the timer registers in this frame.

juno: Add a check to verify BL2 to BL31 plat. param ...

This concerns only debug builds. In BL2, we now pass a special value
to BL3-1 through x1. In BL3-1, we check that we receive the correct
value. This ensures that any platform set value is correctly passed
from BL2 to BL3-1.

juno: Move BL3-1 arguments from normal DRAM to trusted RAM ...

On Juno, BL3-1 arguments used to sit at the beginning of the normal
DRAM. This patch moves them in trusted RAM. BL2 now allocates them
as a platform-specific static variable. BL3-1 then copies them
internally before the MMU is enabled.

Revert commit "Workaround: Setup register context for BL3-3" ...

This reverts commit 033c52b
because the workaround it introduced is no longer needed since
BL3-1 interface rework.

This does not revert the change on BL33 base address on Juno, though.

juno: Limit BL3-1 read/write access to SRAM ...

At present BL3-1 has access to all of the SRAM, including
regions that are mapped as read-only and non-cacheable by other
firmware images.

This patch restricts BL3-1 to only be able to read/write from
memory used for its own data sections

juno: Provide per-EL MMU setup functions ...

Instead of having a single version of the MMU setup functions for all
bootloader images that can execute either in EL3 or in EL1, provide
separate functions for EL1 and EL3. Each bootloader image can then
call the appropriate version of these functions. The aim is to reduce
the amount of code compiled in each BL image by embedding only what's
needed (e.g. BL1 to embed only EL3 variants).

juno: Fix build errors due to recent changes ...

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.

Revert "juno: Initialise architected timer in BL3-1" ...

This reverts commit ff7480a.
because the architected timer is now initialised in architecture
code and no longer in platform code. See commit 9e86490f8f1.

juno: Initialise UART console in all bootloader stages ...

Ensure that each bootloader stage initializes the UART console
independently. As a result, both BL3-1 and BL2 platform code now
calls console_init() instead of relying on BL1 to perform console
setup.

Also perform the console initialisation earlier in BL1 because
it must be done before it is used e.g. through a printf() call
in an assert() statement.

juno: Use static declaration of bl31_args ...

Juno doesn't have TZDRAM as FVP does, and there is real reason why we
need a special memory region for bl31_args anyway, assuming we take care
to copy it in BL31 before BL2's memory is reused.
