Remove calling CPU mpidr from bakery lock API
...
The bakery lock code currently expects the calling code to pass
the MPIDR_EL1 of the current CPU.
This is not always done correctly. Also the change to provide
inline access to system registers makes it more efficient for the
bakery lock code to obtain the MPIDR_EL1 directly.
This change removes the mpidr parameter from the bakery lock
interface, and results in a code reduction of 160 bytes for the
ARM FVP port.
Fixes ARM-software/tf-issues#213

Correctly dimension the PSCI aff_map_node array
...
The array of affinity nodes is currently allocated for 32 entries
with the PSCI_NUM_AFFS value defined in psci.h. This is not enough
for large systems, and will substantially over allocate the array
for small systems.
This patch introduces an optional platform definition
PLATFORM_NUM_AFFS to platform_def.h. If defined this value is
used for PSCI_NUM_AFFS, otherwise a value of two times the number
of CPU cores is used.
The FVP port defines PLATFORM_NUM_AFFS to be 10 which saves
nearly 1.5KB of memory.

Eliminate psci_suspend_context array
...
psci_suspend_context is an array of cache-line aligned structures
containing the single power_state integer per cpu. This array is
the only structure indexed by the aff_map_node.data integer.
This patch saves 2KB of BL3-1 memory by placing the CPU
power_state value directly in the aff_map_node structure. As a
result, this value is now never cached and the cache clean when
writing the value is no longer required.
Fixes ARM-software/tf-issues#195

Initialise CPU contexts from entry_point_info
...
Consolidate all BL3-1 CPU context initialization for cold boot, PSCI
and SPDs into two functions:
* The first uses entry_point_info to initialize the relevant
cpu_context for first entry into a lower exception level on a CPU
* The second populates the EL1 and EL2 system registers as needed
from the cpu_context to ensure correct entry into the lower EL
This patch alters the way that BL3-1 determines which exception level
is used when first entering EL1 or EL2 during cold boot - this is now
fully determined by the SPSR value in the entry_point_info for BL3-3,
as set up by the platform code in BL2 (or otherwise provided to BL3-1).
In the situation that EL1 (or svc mode) is selected for a processor
that supports EL2, the context management code will now configure all
essential EL2 register state to ensure correct execution of EL1. This
allows the platform code to run non-secure EL1 payloads directly
without requiring a small EL2 stub or OS loader.

Remove broken assertion in console_putc()

Remove re-initialisation of system timers after warm boot for FVP
...
This patch removes the reinitialisation of memory mapped system timer
registers after a warm boot for the FVP. The system timers in FVP are
in the 'Always ON' power domain which meant the reinitialisation was
redundant and it could have conflicted with the setup the normal
world has done.
The programming of CNTACR(x) and CNTNSAR, the system timer registers,
are removed from the warm boot path with this patch.

Per-cpu data cache restructuring
...
This patch prepares the per-cpu pointer cache for wider use by:
* renaming the structure to cpu_data and placing in new header
* providing accessors for this CPU, or other CPUs
* splitting the initialization of the TPIDR pointer from the
initialization of the cpu_data content
* moving the crash stack initialization to a crash stack function
* setting the TPIDR pointer very early during boot
