H. Peter Anvin ae7bd11b47 clocksource: Change __ARCH_HAS_CLOCKSOURCE_DATA to a CONFIG option
The machinery for __ARCH_HAS_CLOCKSOURCE_DATA assumed a file in
asm-generic would be the default for architectures without their own
file in asm/, but that is not how it works.

Replace it with a Kconfig option instead.

Andy Lutomirski 433bd805e5 clocksource: Replace vread with generic arch data
The vread field was bloating struct clocksource everywhere except
x86_64, and I want to change the way this works on x86_64, so let's
split it out into per-arch data.
