phy: rockchip-snps-pcie3: only look for rockchip,pipe-grf on rk3588

Browse Source 
The rockchip,pipe-grf property is only used on rk3588, but not on
rk3568. Therefore this property is not present on rk3568 devices,
leading to the following message:

  rockchip-snps-pcie3-phy fe8c0000.phy: failed to find rockchip,pipe_grf regmap

Fix that by only looking for this property on rk3588.
