fix(s32g274a): workaround for ERR051700 erratum

ERR051700 erratum is present on all S32CC-based SoCs and relates to
reset. Releasing multiple Software Resettable Domains (SRDs) from
reset simultaneously, may cause a false error in the fault control
unit.

The workaround is to clear the SRD resets sequentially instead of
simultaneously.

+SoC Errata Workarounds
+----------------------
+
+The S32G274A port of the TF-A includes compilation flags that can be used to
+control the workaround for the SoC. These flags are used similarly to how the
+:ref:`arm_cpu_macros_errata_workarounds` are used. The list of workarounds
+includes the following switches:
+
+-  ``ERRATA_S32_051700``: This applies erratum ERR051700 workaround to
+   SoCs part of the S32 Common Chassis family, and therefore it needs to
+   be enabled for the S32G and S32R devices.
