phy: marvell: fix handling of unconnected comphy
- the default value of comphy pipe selector is set to PCIe (x4)
in case of unconnected comphy the default value remains 0x4
which may lead to several issues with comphy initialization.
- this patch adds SMC call that powers off the comphy lane in case of
unconnected comphy.
