ARM: davinci: clk framework support for enable/disable functionality

Davinci clock framework currently not supporting clock enable/disable
functionality on clock nodes. In Davinci platform EHRPWM module requires
support for clock enable/disable for TBCLK support. Hence this patch
adds support for enabling/disabling clocks depends on the availability
of the functionality.

pwm: pwm-test: Driver support for PWM module testing

As with new PWM framework, PWM functionality is completely controlled by
client drivers. But sometimes it causes issues for testing the PWM
features. So here proposing a pwm-test client driver for testing PWM
functionality. pwm-test driver exposes sysfs entries such as
request, period, duty, config, run, polarity for configuring PWM device.
As the pwm-test driver obligated to PWM framework, this can be used for
testing any PWM hardware.
