PCI: dw: rockchip: Fix s2r failure

Browse Source 
Before commit 7f84caccd0 ("PCI: dw: rockchip: Define IO and Host
initialization interfaces"), ret is getting from rk_pcie_disable_power()
which should never fail actually. Now the final ret is getting from
phy_validate() which could return -EOPNOTSUPP. But we didn't care about
it if phy_validate() isn't implemented. So we see:

[   13.573777] rk-pcie fe150000.pcie: PM: dpm_run_callback(): genpd_suspend_noirq+0x0/0x60 returns -95
[   13.573800] rk-pcie fe150000.pcie: PM: failed to suspend async: error -95

Fix it by return zero to restore the previous behaviour.
