Enable CVE-2017-5715 option to set the IBE bit. This enables kernel workarounds necessary for the said CVE.

With this enabled, Linux reports: CPU0: Spectre v2: using BPIALL workaround

This workaround may need to be re-applied in OS environment around low power transition resume states where context of ACR would be lost (off-mode etc).
