Enable CVE_2017_5715 mitigation on CPU0 on R-Car H2, M2W, M2N, V2H,
which all contain Cortex-A15 cores. R-Car E2 contains only Cortex-A7
cores and is not affected. Without this enabled, Linux kernel reports:
CPU0: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable
With this enabled, Linux kernel reports:
CPU0: Spectre v2: using ICIALLU workaround
NOTE: This by itself does not enable the workaround for other CPUs
than CPU0 and may require additional kernel patches for the
other CPUs in SMP configurations.
