Subject: [PATCH 3/6] ARM: imx: build pm-imx5 code only when PM is enabled

This moves the imx5 pm code out of the list of unconditionally
compiled files for imx5, mirroring what we already do for imx6
and how it was done before the code was move from mach-mx5 to
mach-imx in v3.3.

Without this patch, building with CONFIG_PM disabled results in:

arch/arm/mach-imx/pm-imx5.c:202:116: error: redefinition of 'imx51_pm_init'
arch/arm/mach-imx/include/mach-imx/common.h:154:91: note: previous definition of 'imx51_pm_init' was here
arch/arm/mach-imx/pm-imx5.c:209:116: error: redefinition of 'imx53_pm_init'
arch/arm/mach-imx/include/mach-imx/common.h:155:91: note: previous definition of 'imx53_pm_init' was here
