Subject: [PATCH] AVR32:  Drop support for redundant "keepinitrd" boot-time
 parm.

Given the existing "retain_initrd" boot-time parameter defined in
init/initramfs.c, there appears to be no need for the equivalent
"keepinitrd" parameter.

  not compile-tested, so i'll leave it with haavard to make the final
call.

  the arm architecture also defines that same parm, and it may very
well be redundant, too.
