Will Deacon fc10eff5a2 arm64: errata: Mitigate TLBI errata on Microsoft Azure Cobalt 100 CPU 
commit 1940e70a8144bf75e6df26bf6f600862ea7f7ea1 upstream.

Commit fb091ff394 ("arm64: Subscribe Microsoft Azure Cobalt 100 to ARM
Neoverse N2 errata") states that Microsoft Azure Cobalt 100 CPU "is a
Microsoft implemented CPU based on r0p0 of the ARM Neoverse N2 CPU, and
therefore suffers from all the same errata.".

So enable the workaround for the latest broadcast TLB invalidation bug
on these parts.
