nyan: Initialize the ARM architectural timer in the RAM stage.

Browse source 
This could be done much sooner in the generic timer initialization, but it's
not used by coreboot and, if it's done in the RAM stage, it would be
updateable when using early firmware selection.

BUG=None
TEST=Before setting up these timers, the Linux kernel behaved very poorly and
would hang, trip the watchdog timer, and/or otherwise crash. After setting
them up those problems were no longer noticeable.
BRANCH=None
