  firmware: smccc: Support optional Arm SMCCC SOC_ID name (2025-03-03 14:53:46 +0000)

----------------------------------------------------------------
Arm SMCCC update for v6.15

Just a single update introducing the support for the optional SOC_ID
name string from the Arm SMCCC v1.6 specification.

If the SOC_ID name string is implemented, the machine field of the SoC
Device Attributes will reflect it.

The original intent of SOC_ID was to provide a JEP-106 code for the SiP
and the SoC revision to uniquely identify the SoC. However, there has
been a request to add this optional name so that SoC firmware can
directly provide the SoC name to the OS.

This change avoids the need for frequent updates to various tools that
would otherwise require maintaining hardcoded model/machine name tables
for new SoCs.
