Subject: [PATCH 2/9] phy: ti: j721e-wiz: Get PHY properties only for "phy" subnode

"serdes" node (child node of WIZ) can have sub-nodes for representing links
or it can have sub-nodes for representing the various clocks within the
serdes. Instead of trying to read "reg" from every child node used for
assigning "lane_phy_type", read only if the child node's name is "phy".
