[PATCH 1/2] arch: arm: Correct the dependency of HAVE_ARM_TWD

Original mpcore_wdt config dependency is as follow:
MPCORE_WATCHDOG -> HAVE_ARM_TWD -> SMP -> (CPU_V6K || CPU_V7)
This patch will remove SMP and made the dependency as follow:
MPCORE_WATCHDOG -> HAVE_ARM_TWD -> (CPU_V6K || CPU_V7)

The MPCore watchdog (and timer) can be found at ARM11 MPCore (CPU_V6K) and
Cortex A9 MPCore (CPU_V7). The dependency between MPCORE_WATCHDOG and
(CPU_V6K || CPUV7) is necessary, but the dependency of SMP is redundant.
The MPCore watchdog should function normally even SMP is not turned on with
ARM11 or Cortex A9 CPU.
