arm64: KVM: Drop hyp_alternate_select for checking for ARM64_WORKAROUND_834220

Browse source

There is no reason for using hyp_alternate_select when checking
for ARM64_WORKAROUND_834220, as each of the capabilities is
also backed by a static key. Just replace the KVM-specific
construct with cpus_have_const_cap(ARM64_WORKAROUND_834220).
