[PATCH] clocksource: add __ro_after_init to cyclecounter

[Bhumika Goyal]

The object cyclecounter of type cyclecounter is not getting modified
after getting initialized by arch_counter_register. Apart from
initialization in arch_counter_register it is also passed as an argument
to the function timecounter_init but this argument is of type const.
Therefore, add __ro_after_init to its declaration.
