kernel/modules: add chaoskey module, hardware TRNG

Browse source 
Package the driver for Chaoskey, a USB dongle that provides a
True Random Number Generator (TRNG) and feeds entropy to kernel.

Chaoskey driver is included the upstream Linux sources, so
only packaging it is needed.

Run-tested with ipq806x/R7800 and mvebu/WRT3200ACM.

(Requires CONFIG_HW_RANDOM kernel option.)
