clocksource/drivers/arm_arch_timer: Remove fsl-a008585 parameter 

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.

[ARM64]
Format: <bool>
Enable/disable the workaround of Freescale/NXP
erratum A-008585. This can be useful for KVM
guests, if the guest device tree doesn't show the
erratum. If unspecified, the workaround is
enabled based on the device tree.
