[v4,2/4] riscv: dts: fix the icicle's #pwm-cells

\#pwm-cells for the Icicle kit's fabric PWM was incorrectly set to 2 &
blindly overridden by the (out of tree) driver anyway. The core can
support inverted operation, so update the entry to correctly report its
capabilities.

Gah, I messed this patch up... I'll resend.
