With the "real HZ" debate out of the way, let's actually
use the apm821xx's default upstream config file at
arch/powerpc/configs/44x/bluestone_defconfig. From what
I can tell, it sets NO_HZ (well, this platform was for
NAS, so this is a bit unexpected) and remove any specific
HZ_$VALUE symbol.
Sadly, Daniel Engberg didn't run any before/after netperf
tests, because it would have been such a slam dunk across
the boards. In case of the apm821xx the tcp tx/rx
performance improved ~14% (from 600Mbps to 700Mps).
This now causes the emac to drop frames too, so let's see
if this is causes more problems or not.
This patch includes a refresh of the configuration too.

Most targets upstream use 250Hz or even 1000Hz by default while
100Hz is hardcoded in OpenWrt's default config. Use upstream default
except for apm821xx which hardsets 1000Hz instead of platform default of
250Hz.
