crypto: api - remove CRYPTOA_U32 and related functions

Browse Source 
According to the advice of Eric and Herbert, type CRYPTOA_U32
has been unused for over a decade, so remove the code related to
CRYPTOA_U32.

After removing CRYPTOA_U32, the type of the variable attrs can be
changed from union to struct.
