crypto: inside-secure - Only enable algorithms advertised by the hardware
This patch probes the supported algorithms from the hardware and only
registers the ones that the hardware actually supports. This is necessary
because this is a generic driver supposed to run on a wide variety of
engines, which may or may not implement certain algorithms.
