Clean usage of void pointers to access symbols

psci: initialize array fully to comply with MISRA

Initializes each element of the last_cpu_in_non_cpu_pd array in PSCI
stat implementation to -1, the reset value. This satisfies MISRA rule
9.3.

Previously, only the first element of the array was initialized to -1.

Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

Don't make build results depend on dependency files

Change PLATFORM_ROOT to TF_PLATFORM_ROOT

Rename 'smcc' to 'smccc'

tegra: Use SPDX license identifier

When the source code says 'SMCC' it is talking about the SMC Calling
Convention. The correct acronym is SMCCC. This affects a few definitions
and file names.

Some files have been renamed (smcc.h, smcc_helpers.h and smcc_macros.S)
but the old files have been kept for compatibility, they include the
new ones with an ERROR_DEPRECATED guard.

there are two fix for save/restore watchdog register:
1. watchdog plck will shutdown after secure_watchdog_disable(), so need
   to save register before it and restore after secure_watchdog_enable().
2. need write 0x76 to cnt_restart to keep watchdog alive when restore
   watchdog register.

x3 will be assigned by the folloing instructions.
So the first instruction is not needed any more.

old method:
  (ClusterId * FVP_MAX_CPUS_PER_CLUSTER)
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId

it should be
  (ClusterId * FVP_MAX_CPUS_PER_CLUSTER) * FVP_MAX_PE_PER_CPU
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId

which can be simplified as:
(ClusterId * FVP_MAX_CPUS_PER_CLUSTER + CPUId) * FVP_MAX_PE_PER_CPU + ThreadId

The FVP platform port for SP_MIN (BL32) didn't map the flash memory
in BL32 for stroring the mem_protect enable state information leading
to synchronous exception. The patch fixes it by adding the region to
the BL32 mmap tables.

Implement support for v1.2 of firmware interfaces spec (ARM DEN 0070A)

When querying `SMCCC_ARCH_WORKAROUND_1` through `SMCCC_ARCH_FEATURES`,
return either:
  * -1 to indicate the PE on which `SMCCC_ARCH_FEATURES` is called
    requires firmware mitigation for CVE-2017-5715 but the mitigation
    is not compiled in.
  * 0 to indicate that firmware mitigation is required, or
  * 1 to indicate that no firmware mitigation is required.

This patch complies with v1.2 of the firmware interfaces
specification (ARM DEN 0070A).
