Let's keep sane defaults, but not make it unreasonable to tweak eaither.
I suggest what has already been mentioned.
Register both timers, but have the sync timer have a higher rating. On
AMxxx where there is no sync timer, GPtimer will be used.
For those who want to use GPtimer, they can boot using clocksource= to
override the default.
Santosh is right, GPtimer will not work on a PM enabled kernel, but
there are lots of ways to use the cmdline to get a non-working kernel,
so that's OK by me.
Let's just ensure that the boot-defaults are sane.
