C6X: fix timer64 initialization
Some SoCs have a timer block enable controlled through the DSCR registers. There is a problem in the timer64 driver initialization where the code accesses a timer register to get the divisor used to calculate timer clock rate. If the timer block has not been enabled when this register read takes place, an exception is generated. This patch makes sure that the timer block is enabled before accessing the registers.
