[PATCH v8 03/11] PCI: imx6: Fix missing call to phy_power_off() in error handling

Fix missing call to phy_power_off() in the error path of
imx6_pcie_host_init(). Remove unnecessary check for imx6_pcie->phy as the
PHY API already handles NULL pointers.

Fixes: cbcf8722b523 ("phy: freescale: imx8m-pcie: Fix the wrong order of phy_init() and phy_power_on()")
