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.
