[PATCH 2/2] cpuidle / calxeda: remove redundant Kconfig option

[Daniel Lezcano]

When the CPU_IDLE and the ARCH_HIGHBANK options are set it is
pointless to define a new option CPU_IDLE_CALXEDA because it
is redundant.

The Makefile drivers directory contains a condition to compile
the cpuidle drivers:

obj-$(CONFIG_CPU_IDLE)          += cpuidle/

Hence, if CPU_IDLE is not set we won't enter this directory.

This patch removes the useless Kconfig option and replaces the
condition in the Makefile by CONFIG_ARCH_HIGHBANK.
