riscv: dts: microchip: fix the icicle's #pwm-cells

[ Upstream commit bdd28ab35c163553a2a686fdc5ea3cf247aad69b ]

\#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.
