[media] ARM: DT: STi: stihxxx-b2120: Add pulse-width properties to ssc2 & ssc3
Adding these properties makes the I2C bus to the demodulators much more reliable, and we no longer suffer from I2C errors when tuning. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
