Jon Hunter 5eccd0d9fa pwm: tegra: Ensure the clock rate is not less than needed 
When dynamically scaling the PWM clock, the function
dev_pm_opp_set_rate() may set the PWM clock to a rate that is lower than
what is required. The clock rate requested when calling
dev_pm_opp_set_rate() is the minimum clock rate that is needed to drive
the PWM to achieve the required period. Hence, if the actual clock
rate is less than the requested clock rate, then the required period
cannot be achieved and configuring the PWM fails. Fix this by
calling clk_round_rate() to check if the clock rate that will be provided
is sufficient and if not, double the required clock rate to ensure the
required period can be attained.

Fixes: 8c193f4714 ("pwm: tegra: Optimize period calculation")
