Samsung non-critical fixes for v4.1

Browse Source 
- mostly trivial build fixes with random configurations
   from Arnd Bergmann
 
   for s3c24xx:
   avoid a Kconfig warning and fix header file inclusions,
   and fix building without PM_SLEEP and use SAMSUNG_WAKEMASK
 
   for s3c64xx:
   fix __initdata section mismatch and add I2C dependencies,
   and fix building with PM_SLEEP
