Subject: [PATCH 2/2] [RFC] arm64: Add dependencies to vendor-specific errata

Currently the user is asked about enabling support for each and every
vendor-specific erratum, even when support for the specific platform is
not enabled.

Fix this by adding platform dependencies to the config options
controlling support for vendor-specific errata.

Note that FUJITSU_ERRATUM_010001 is left untouched, as no config symbol
exists for the Fujitsu A64FX platform.
