arm64: dts: marvell: cn9132-clearfog: fix multi-lane pci x2 and x4 ports



commit 794a0666 upstream.

The mvebu-comphy driver does not currently know how to pass correct
lane-count to ATF while configuring the serdes lanes.

This causes the system to hard reset during reconfiguration, if a pci
card is present and has established a link during bootloader.

Remove the comphy handles from the respective pci nodes to avoid runtime
reconfiguration, relying solely on bootloader configuration - while
avoiding the hard reset.

When bootloader has configured the lanes correctly, the pci ports are
functional under Linux.

This issue may be addressed in the comphy driver at a future point.

Fixes: e9ff907f ("arm64: dts: add description for solidrun cn9132 cex7 module and clearfog board")
