Govindraj Raja 5f32fd2145 fix(cpus): workaround for Neoverse-V3 erratum 2970647
Neoverse V3 erratum 2970647 that applies to r0p0 and is fixed in r0p1.

In EL3, reads of MPIDR_EL1 and MIDR_EL1 might incorrectly virtualize
which register to return when reading the value of
MPIDR_EL1/VMPIDR_EL2 and MIDR_EL1/VPIDR_EL2, respectively.

The workaround is to do an ISB prior to an MRS read to either
MPIDR_EL1 and MIDR_EL1.
