ARM: dts: lpc32xx: Add #pwm-cells property to the two SoC PWMs

If these PWMs are to be used, a #pwm-cells property is necessary. The
right location for that is in the SoC's dtsi file to not make
machine.dts files repeat the value for each usage. Currently the
machines based on nxp/lpc/lpc32xx.dtsi don't make use of the PWMs, so
there are no properties to drop there.
