John Powell f2bd352820 fix(errata): workaround for Cortex-A510 erratum 2971420 
Cortex-A510 erratum 2971420 applies to revisions r0p1, r0p2, r0p3,
r1p0, r1p1, r1p2 and r1p3, and is still open.

Under some conditions, data might be corrupted if Trace Buffer
Extension (TRBE) is enabled. The workaround is to disable trace
collection via TRBE by programming MDCR_EL3.NSTB[1] to the opposite
value of SCR_EL3.NS on a security state switch. Since we only enable
TRBE for non-secure world, the workaround is to disable TRBE by
setting the NSTB field to 00 so accesses are trapped to EL3 and
secure state owns the buffer.
