[PATCH v2] phy: freescale: imx8m-pcie: Fix the wrong order of phy_init() and phy_power_on()

[Richard Zhu]

Refer to phy_core driver, phy_init() must be called before phy_power_on().
Fix the wrong order of phy_init() and phy_power_on() here.
Squash the changes into one patch to avoid the possible bi-section hole.

Fixes: 1aa97b002258 ("phy: freescale: pcie: Initialize the imx8 pcie standalone phy driver")
