CAR size and CAR base defines are scattered all over the place. Set them

centrally from Kconfig, but keep the Kconfig variables hidden.
That way, they are available everywhere, you don't have to try to guess
where they are set, and they come with help text if you look at
arch/x86/Kconfig.
No semantic changes, although some of the settings really could use an
overhaul.

This also is a requirement for my printk buffer patch.
