[PATCH 1/2] Revert "arm64: dts: marvell: cn9132-clearfog: fix multi-lane pci x2 and x4 ports"

[Josua Mayer]

This reverts commit 794a066688038df46c01e177cc6faebded0acba4 because it
misunderstood interworking between arm trusted firmware and the common
phy driver, and does not consistently resolve the issue it was intended
to address.

Further diagnostics have revealed the root cause for the reported system
lock-up in a race condition between pci driver probe and clock core
disabling unused clocks.

Revert the wrong change restoring driver control over all pci lanes.
As a temporary workaround for the original issue, users can boot with
"clk_ignore_unused".
