ice: fix PHY Clock Recovery availability check
[ Upstream commit 01fd68e54794fb1e1fe95be38facf9bbafee9ca3 ]
To check if PHY Clock Recovery mechanic is available for a device, there
is a need to verify if given PHY is available within the netlist, but the
netlist node type used for the search is wrong, also the search context
shall be specified.
Modify the search function to allow specifying the context in the
search.
Use the PHY node type instead of CLOCK CONTROLLER type, also use proper
search context which for PHY search is PORT, as defined in E810
Datasheet [1] ('3.3.8.2.4 Node Part Number and Node Options (0x0003)' and
'Table 3-105. Program Topology Device NVM Admin Command').
