KVM: arm64: Enable Cortex-A510 erratum 2077057 by default

[ Upstream commit 4c11113c1a3d10f5b617e5d2b9acd8d1d715450f ]

The recently added configuration option for Cortex A510 erratum 2077057 does
not have a "default y" unlike other errata fixes. This appears to simply be
an oversight since the help text suggests enabling the option if unsure and
there's nothing in the commit log to suggest it is intentional.
