Use new field "num_of_modules" of MGPIR register for "hwmon" interface in order to get the number of modules supported by system directly from the system configuration, instead of getting it from port to module mapping info.
Reading this info through MGPIR register is faster and does not depend on possible dynamic re-configuration of ports. In case of port dynamic re-configuration some modules can logically "disappear" as a result of port split and un-spilt operations, which can cause missing of some modules, in case this info is taken from port to module mapping info.
