[PATCH v1 17/23] phy: marvell: fix handling of unconnected comphy

[Stefan Roese]

From: Christine Gharzuzi <chrisg at marvell.com>

- 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.
