hw/riscv: clint: Avoid using hard-coded timebase frequency
At present the CLINT timestamp is using a hard-coded timebase
frequency value SIFIVE_CLINT_TIMEBASE_FREQ. This might not be
true for all boards.
Add a new 'timebase-freq' property to the CLINT device, and
update various functions to accept this as a parameter.
