mlxsw: core: Add an infrastructure to track transceiver overheat counter
Initialize an array that stores per-module overheat state and a counter indicating how many times the module was in overheat state. Export a function to query the counter according to module number. Will be used later on by the switch driver (i.e., mlxsw_spectrum) to expose module's overheat counter as part of ethtool statistics. Initialize mlxsw_env after driver initialization to be able to query number of modules from MGPIR register.
