ARM: OMAP3/4: consolidate cpuidle Makefile
The current Makefile compiles the cpuidle34xx.c and cpuidle44xx.c files even if the cpuidle option is not set in the kernel. This patch fixes this by creating a section in the Makefile where these files are compiled only if the CONFIG_CPU_IDLE option is set. This modification breaks an implicit dependency between CPU_IDLE and PM as they belong to the same block in the Makefile. This is fixed in the Kconfig by selecting explicitely PM is CPU_IDLE is set. The linux coding style recommend to use no-op functions in the headers when the subsystem is disabled instead of adding big section in C files. This patch fix this also.
