fix(cpus): workaround for Cortex-A720 erratum 2926083
Cortex-A720 erratum 2926083 is a Cat B erratum that is present
in revisions r0p0, r0p1 and is fixed in r0p2. The errata is only
present when SPE (Statistical Profiling Extension) is implemented
and enabled.
The workaround is to set bits[58:57] of the CPUACTLR_EL1 to 'b11
when SPE is "implemented and enabled".
