phy: marvell: mux: Support nontrivial node order in selector register
Currently comphy_mux supports only trivial order of nodes in pin
selector register, that is lane N on position N*bitcount.
Add support for nontrivial order, with map stored in device tree
property mux-lane-order.
This is needed for Armada 37xx.
As far as I know, there is no driver for Armada 37xx comphy in the
kernel. When such a driver comes, this will need to be rewritten to
support the device tree bindings from the kernel.
