Allow FP register context to be optional at build time
...
CTX_INCLUDE_FPREGS make variable allows us to include or exclude FP
registers from context structure, in case FP is not used by TSPD.

Support later revisions of the Foundation FVP
...
The code in the FVP port which checks the platform type and
revision information in the SYS_ID register strictly supported
only the first revision of the Base and Foundation FVPs.
The current check also does not reflect the fact that the
board revision field is 'local' to the board type (HBI field).
Support for a new Foundation model is required now, and the
checking code is relaxed to allow execution (with a diagnostic)
on unrecognised revisions of the Base and Foundation FVP.

Remove current CPU mpidr from PSCI common code
...
Many of the interfaces internal to PSCI pass the current CPU
MPIDR_EL1 value from function to function. This is not required,
and with inline access to the system registers is less efficient
than requiring the code to read that register whenever required.
This patch remove the mpidr parameter from the affected interfaces
and reduces code in FVP BL3-1 size by 160 bytes.

fvp: Fix register name in 'plat_print_gic_regs' macro
...
The 'plat_print_gic_regs' macro was accessing the GICC_CTLR register
using the GICD_CTLR offset. This still generates the right code in
the end because GICD_CTLR == GICC_CTLR but this patch fixes it for
the logic of the code.

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.

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.

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.
