Hi Conor,

I apologize for forgetting about this update earlier. Just now,
I tried to pull rebase master and noticed that other developers seem
to have made some fixes to the algorithm. Upon closer inspection, I
found that they addressed the part we previously discussed with Emil
and Uwe, such as "first pwm_apply_state."

Therefore, my instinct tells me that they have already taken care of
the issues we discussed before.

I will review the conflicting parts in the pwm-sifive.c code in my v4
version once again to ensure there are no omissions. If I find any, I
will submit v5 accordingly.

This removes the active-low properties of the PWM-controlled LEDs in
the HiFive Unmatched device tree.

Since there is no PWM driver patch for this to go along with, this ack
doesn't mean anything anymore. Please drop it if you resubmit.
