At the moment we have the workaround for the Freescale arch timer
erratum A-008585 merged into the generic timer_read_counter()
routine.
Split those two up, so that we can add other errata workaround more
easily. Also add an explaining comment on the way.

Are these these two patches are for coming release?
Yes, please. That's an issue that needs fixing now. The bug is in all
A64 silicon, but the issue popped up with the recent commit
5ff8e54888e4
and can be triggered quite easily:
Boot mainline U-Boot on any A64 board, and do:
ls mmc 0:1
on any SD card (with at least one partition defined). Then hold down
the
Enter key to repeat this last command over and over again. It usually
takes less than 10 seconds to crash the board.
People reported immediate crashes under certain circumstances (GPT
partitioned SD cards):

Cheers,
Andre.
For fixing the issue we also need to add the compat to the timer in the
dts so kernels will also Apply the errata.
Booting is cool but if you boot a kernel that will have timer issue
it's not that great.
