arm64: dts: rockchip: Fix PCI node addresses on rk3399-gru

[ Upstream commit c13c823a78b77ea0e5f1f73112d910e259911101 ]

The rk3399-gru PCI node addresses are wrong.

In rk3399-gru-scarlet, the bus number in the address should be 0. This is
because bus number assignment is dynamic and not known up front. For FDT,
the bus number is simply ignored.

In rk3399-gru-chromebook, the addresses are simply invalid. The first
"reg" entry must be the configuration space for the device. The entry
should be all 0s except for device/slot and function numbers. The existing
64-bit memory space (0x83000000) entries are not valid because they must
have the BAR address in the lower byte of the first cell.

Warnings for these are enabled by adding the missing 'device_type = "pci"'
for the root port node.
