arm64: cpufeature: Enable Qualcomm Falkor errata 1009 for Kryo
The Kryo cores share errata 1009 with Falkor, so add their model definitions and enable it for them as well. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> [will: Update entry in silicon-errata.rst] Signed-off-by: Will Deacon <will@kernel.org>
