The ebsa110 platform is the last thing that uses
CONFIG_ARCH_USES_GETTIMEOFFSET, and Russell has previously said that he
thinks the platform can be retired now.

Removing it allows us clean up the timer code by throwing out all of
the references to arch_gettimeoffset().

The am79c961a network driver can presumably also go, as no other platform
references it.

I don't expect these to make it into the coming merge window, posting here
as an RFC, and as a reference for the mildly related timer tick series.

As far as I know, that is correct; it's rather specific to the
platform.
