[TMS320F28379] implement PWM driver (#6457)
增加c28x芯片的pwm驱动
已经在TMS320F28379中通过测试
pwm设备框架增加如下方法:
#define PWM_CMD_SET_DEAD_TIME (RT_DEVICE_CTRL_BASE(PWM) + 8)
#define PWM_CMD_SET_PHASE (RT_DEVICE_CTRL_BASE(PWM) + 9)
#define PWM_CMD_ENABLE_IRQ (RT_DEVICE_CTRL_BASE(PWM) + 10)
#define PWM_CMD_DISABLE_IRQ (RT_DEVICE_CTRL_BASE(PWM) + 11)
