Rafael Beims 24d759976a phy: freescale: imx8m-pcie: assert phy reset during power on ...

commit f2ec4723de upstream.

After U-Boot initializes PCIe with "pcie enum", Linux fails to detect
an NVMe disk on some boot cycles with:

  phy phy-32f00000.pcie-phy.0: phy poweron failed --> -110

Discussion with NXP identified that the iMX8MP PCIe PHY PLL may fail to
lock when re-initialized without a reset cycle [1].

The issue reproduces on 7% of tested hardware platforms, with a 30-40%
failure rate per affected device across boot cycles.

Insert a reset cycle in the power-on routine to ensure the PHY is
initialized from a known state.
