Subject: [PATCH 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.
Fixes: 72560c6559b8 ("riscv: dts: microchip: add fpga fabric section to icicle kit")
