The SGI/RD platforms have been using PSCI state ID format as defined in
PSCI version prior to 1.0. This is being changed and the PSCI extended
state ID format as defined in PSCI version 1.1 is being adapted. In
addition to this, the use of Arm recommended PSCI state ID encoding is
enabled as well.

Two issues in documentation were identified after the release.
This patch fixes these typos.

1. Matternhorn ELP CPU was made available through v2.5 release, not
   Matternhorn CPU
2. We had upgraded TF-A to use GCC 10.2 toolchain family and used this
   toolchain for release testing

Add SMC wrappers for handshaking the existence
and basic parameter validation for the SMCCC/PCI
API. The actual read/write/segment validation is
implemented by a given platform which will enable
the API by defining SMC_PCI_SUPPORT.

The SMCCC, part 3 indicates that only the bottom
32-bits of a 32-bit SMC call are valid. The upper
bits must be zero. Lets enforce that so standard
service code can assume its been called that way.

Added support for HW computed CRC using Arm ACLE intrinsics.
These are built-in intrinsics available for ARMv8.1-A, and
onwards.
These intrinsics are enabled via '-march=armv8-a+crc' compile
switch for ARMv8-A (supports CRC instructions optionally).

HW CRC support is enabled unconditionally in BL2 for all Arm
platforms.

HW CRC calculation is verified offline to ensure a similar
result as its respective ZLib utility function.

HW CRC calculation support will be used in the upcoming
firmware update patches.

* changes:
  docs(prerequisites): add `--no-save` to `npm install`
  fix(hooks): downgrade `package-lock.json` version

To avoid the mistake fixed by the previous commit, ensure users install
the Node.js dependencies without polluting the lock file by passing
`--no-save` to the `npm install` line.

The NPM lock file was accidentally updated using a later version of
Node.js than required by the prerequisites. This upgraded the lock file
to the v2 format, which causes a warning on Node.js 14 (the
prerequisites version). This moves the lock file back to v1 by
installing the dependencies with Node.js 14.
