crypto: x86/aegis,morus - Fix and simplify CPUID checks
It turns out I had misunderstood how the x86_match_cpu() function works. It evaluates a logical OR of the matching conditions, not logical AND. This caused the CPU feature checks for AEGIS to pass even if only SSE2 (but not AES-NI) was supported (or vice versa), leading to potential crashes if something tried to use the registered algs. This patch switches the checks to a simpler method that is used e.g. in the Camellia x86 code. The patch also removes the MODULE_DEVICE_TABLE declarations which actually seem to cause the modules to be auto-loaded at boot, which is not desired. The crypto API on-demand module loading is sufficient.
