arm64: dts: rockchip: Enable PCIe CLKREQ# for RK3588 on Rock 5b-5bp-5t series

Browse source

Add supports-clkreq and the corresponding pinmux configurations for PCIe
ASPM L1 substates on the Rock 5B, 5B+ and 5T.
The supports-clkreq flag informs the PCIe controller that the hardware
routing for the CLKREQ# sideband signal is present. This enables support
for PCIe ASPM (Active State Power Management) L1 substates, allowing for
better power efficiency.
