clocksource/drivers/arm_arch_timer: Remove fsl-a008585 parameter

commit 5444ea6a7f46276876e94ecf8d44615af1ef22f7 upstream.

Having a command line option to flip the errata handling for a
particular erratum is a little bit unusual, and it's vastly superior to
pass this in the DT. By common consensus, it's best to kill off the
command line parameter.
