[PATCH v3 4/6] rockchip: tpl: change call condition rockchip_stimer_init()

[Johan Jonker <jbx6244@gmail.com>]

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

Changed V3:
  use CONFIG_ROCKCHIP_STIMER

Changed V2:
  use IS_ENABLED
  add include kconfig.h
  move define location so that rockchip_stimer_init() is always
  visible to the compiler
