PCI: tegra: Fix devm_kcalloc() argument order for port->phys allocation

Fix incorrect argument order in devm_kcalloc() when allocating port->phys.
The original call used sizeof(phy) as the number of elements and
port->lanes as the element size, which is reversed.  While this happens to
produce the correct total allocation size with current pointer size and
lane counts, the argument order is wrong.
