[PATCH] i386: let REGPARM no longer depend on EXPERIMENTAL

REGPARM has already gotten much testing, what about removing the
dependency on EXPERIMENTAL?

Additionally, this patch does:
- remove the useless "default n"
- remove note regarding binary only modules (nowadays, there are even
  some binary only modules compiled with REGPARM=y available)

 	Compile the kernel with -mregparm=3. This uses a different ABI
 	and passes the first three arguments of a function call in registers.
-	This will probably break binary only modules.
