If I follow the logic of arch_arm_timer is better than dw_apb timer.

1. The arch_arm_timer is present

  => dw_apb timer is not used at all

  CONFIG_ARM_ARCH_TIMER=y
  # CONFIG_DW_APB_TIMER is not set

2. The arch_arm_timer is *not* present

  => dw_apb_timer is used with delay code

  # CONFIG_ARM_ARCH_TIMER is not set
  CONFIG_DW_APB_TIMER=y

In both cases, DW_APB_TIMER_BASED_DELAY is not needed.

This still has the same problem that running a multi_v7_defconfig
kernel or a binary distro kernel will always enable both. We really
want to have a good run-time decision, not compile-time.
