Banajit Goswami 2ce3013709 ARM: SAMSUNG: Move PWM device definition from plat-s3c24xx to plat-samsung
This patch does the following:-
1. It moves file pwm.c from plat-s3c24xx to plat-samsung. This will
   enable all machines with Samsung SoCs to make use of the same code.
2. The device definitions have been separated to a new file dev-pwm.c
   for better clarity and structure.
3. It will enable all Samsung S3C and S5P series SoC's to use common
   PWM Kconfig definition.
