fix(errata): workaround for Neoverse-N2 erratum 2242400

Neoverse-N2 erratum 2242400 is a Cat B erratum that applies to
revision r0p0 of CPU. It is still open. The workaround
is to set CPUACTLR5_EL1[17] to 1'b1 followed by setting few
system control registers to specific values as per attached
SDEN document.
