[PATCH 5.3 178/193] arm64: cpufeature: Enable Qualcomm Falkor errata 1009 for Kryo

[Greg Kroah-Hartman]

From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>

[ Upstream commit 36c602dcdd872e9f9b91aae5266b6d7d72b69b96 ]

The Kryo cores share errata 1009 with Falkor, so add their model
definitions and enable it for them as well.
