ARM: Migrate errata to Kconfig

This moves all of the current ARM errata from various header files and in to
Kconfig.  This allows for a minor amount of cleanup as we had some instances
where both a general common header file was enabling errata as well as the
board config.  We now just select these once at the higher level in Kconfig
