fix(cpus): workaround for Cortex-A715 erratum 2413290
Cortex-A715 erratum 2413290 is a Cat B erratum that is present
only in revision r1p0 and is fixed in r1p1. The errata is only
present when SPE(Statistical Profiling Extension) is enabled.
The workaround is to set bits[58:57] of the CPUACTLR_EL1 to 'b11
when SPE is enabled, ENABLE_SPE_FOR_NS=1.
