In CPU definitions we should not be explicilty naming peripheral modules to use via USEMODULE (one should use FEATURES_PROVIDED instead). Plus add missing cpu_init() and periph_init() methods. This commit removes periph_hwrng support from the pic32mx cpu builds as pic32mx does not have hwrng only pic32mz does.
