On imx7d the pcie-phy power domain is turned off in suspend and this can make the system hang after resume when attempting any read from PCI. Fix this by adding minimal suspend/resume code. This will prepare for powering down on suspend and reset the block on resume. Code is only for imx7d but a very similar sequence can be used for other SOCs.
