dt-bindings: devfreq: event: rockchip,dfi: Add rk3588 support

This adds rockchip,rk3588-dfi to the list of compatibles. Unlike ealier
SoCs the rk3588 has four interrupts (one for each channel) instead of
only one, so increase the number of allowed interrupts to four.

dt-bindings: devfreq: event: rockchip,dfi: Add rk3568 support

This adds the rockchip,rk3568-dfi compatible to the binding. Make clocks
optional for this SoC as the RK3568 doesn't have a kernel controllable
PCLK.
