Neoverse-N1: workaround mis-ordering of instruction fetches

└─> Neoverse-N1: workaround mis-ordering of instruction fetches
This option adds a workaround for ARM Neoverse-N1 erratum
1542419.
Affected Neoverse-N1 cores could execute a stale instruction when
modified by another CPU. The workaround depends on a firmware
counterpart.
Workaround the issue by hiding the DIC feature from EL0. This
forces user-space to perform cache maintenance.
If unsure, say Y.
