[PATCH -next] ARM: at91: pm: Fix rand build error

[YueHaibing]

If ATMEL_PM is y but PM is n, build fails:

arch/arm/mach-at91/pm.c:1435:13: error: redefinition of ‘at91rm9200_pm_init’
 void __init at91rm9200_pm_init(void)
             ^~~~~~~~~~~~~~~~~~
In file included from arch/arm/mach-at91/pm.c:29:0:
arch/arm/mach-at91/generic.h:19:27: note: previous definition of ‘at91rm9200_pm_init’ was here
 static inline void __init at91rm9200_pm_init(void) { }
                           ^~~~~~~~~~~~~~~~~~

ATMEL_PM should not be enabled independently, it is only selected by Soc.
