[PATCH RFC 5/5] arm64: dts: rockchip: enable PCIE3 controller and phy for Rock5B boards

[Qu Wenruo <wqu@suse.com>]

We only needs to define the needed 3v3 voltage for the PCIE controller,
and enable both the controller and phy.

Since I only own Rock5B boards for RK3588, I can not test for sure for
other boards, thus this patch only enables the PCIE controller/phy for
Rock5B.
