fix(cpus): workaround for Cortex-A725 erratum 3711914

Cortex-A725 erratum 3711914 is a Cat B erratum that applies
to revisions r0p0 and r0p1 and it is fixed in r0p2.

This erratum can be avoided by

fix(cpus): workaround for Cortex-A725 erratum 3711914

Cortex-A725 erratum 3711914 is a Cat B erratum that applies
to revisions r0p0 and r0p1 and it is fixed in r0p2.

This erratum can be avoided by inserting a DMB LD after each DSB ST instruction.

fix(cpus): workaround for Cortex-A725 erratum 2936490

Cortex-A725 erratum 2936490 is a Cat B erratum that applies
to revisions in r0p0, and is fixed in r0p1.

This erratum can be avoided by setting CPUACTLR2_EL1[37] to 1.
Setting this bit is expected to have a negligible performance impact.

fix(cpus): workaround for Cortex-A725 erratum 3699564

Cortex-A725 erratum 3699564 that applies to r0p0, r0p1 and is
fixed in r0p2.

The workaround is for EL3 software that performs context save/restore
on a change of Security state to use a value of SCR_EL3.NS when
accessing ICH_VMCR_EL2 that reflects the Security state that owns the
data being saved or restored.

feat(tc): enable Last-level cache (LLC)

The EXTLLC bit in CPUECTLR_EL1 register indicates that an external
Last-level cache is present in the system.

This bit is not set for CPUs on TC3 platform despite there is
presence of LLC in MCN, so set them.
