rockchip: spl: change call condition rockchip_stimer_init()

The Rockchip SoCs rk3066/rk3188 have no CONFIG_ROCKCHIP_STIMER_BASE
defined. Currently only rk3188 has an exception in SPL. Make this more
generic and compile code inside the function rockchip_stimer_init()
only when CONFIG_ROCKCHIP_STIMER_BASE is available.
