 mips: Use the inline macro version of bswap.
 
 mips suffers from the same problem as sparc where bswap is slow
 and using the GCC builtin does not make it better.
 
 This change improves the speed of disk encryption by around 3 MiB/s
 on an EdgeRouter 4.

 powerpc: Use GCC builtins for bswap.
 
 This doubled disk encryption performance on an (emulated) G4. Further
 improvements are possible if the GCC 2 version of the endian functions
 is used, so we might want to consider doing that on more NetBSD ports.
