arm64: dts: rockchip: rk3588: Add aclk_usb for ehci and ohci controllers

Browse Source 
Test on RK3588 EVB1 with dwc3_of_simple_driver_init in
initcall_blacklist like this:

bootargs = "earlycon=uart8250,mmio32,0xfeb50000 console=ttyFIQ0 irqchip.gicv3_pseudo_nmi=0 initcall_blacklist=dwc3_of_simple_driver_init";

Kernel halt in ehci_bus_resume when read the intr_enable
register of the ehci controller. It's because that the
ehci controllers depend on the aclk_usb which only be
managed by DWC3 controller driver right now.

The clock dependency when access ehci/ohci controller registers:
CPU -> hclk_vo1usbtop -> aclk_usb -> hclk_usb -> ehci/ohci

This patch adds the aclk_usb for all ehci and ohci controllers.
