John Powell fcf2ab71ac fix(cpus): workaround for Cortex-A715 erratum 2804830
Cortex-A715 erratum 2804830 applies to r0p0, r1p0, r1p1 and r1p2,
and is fixed in r1p3.

Under some conditions, writes of a 64B-aligned, 64B granule of
memory might cause data corruption without this workaround. See SDEN
for details.

Since this workaround disables write streaming, it is expected to
have a significant performance impact for code that is heavily
reliant on write streaming, such as memcpy or memset.
