Subject: [PATCH] crypto:vmx: Move ppc vmx diirectory to arch/powerpc/crypto.

Relocate all crypto files in vmx driver to arch/powerpc/crypto directory
and remove vmx directory.

drivers/crypto/vmx/aes.c rename to arch/powerpc/crypto/aes.c
drivers/crypto/vmx/aes_cbc.c rename to arch/powerpc/crypto/aes_cbc.c
drivers/crypto/vmx/aes_ctr.c rename to arch/powerpc/crypto/aes_ctr.c
drivers/crypto/vmx/aes_xts.c rename to arch/powerpc/crypto/aes_xts.c
drivers/crypto/vmx/aesp8-ppc.h rename to arch/powerpc/crypto/aesp8-ppc.h
drivers/crypto/vmx/aesp8-ppc.pl rename to arch/powerpc/crypto/aesp8-ppc.pl
drivers/crypto/vmx/ghash.c rename to arch/powerpc/crypto/ghash.c
drivers/crypto/vmx/ghashp8-ppc.pl rename to arch/powerpc/crypto/ghashp8-ppc.pl
drivers/crypto/vmx/vmx.c rename to arch/powerpc/crypto/vmx.c

deleted files:
drivers/crypto/vmx/Makefile
drivers/crypto/vmx/Kconfig
drivers/crypto/vmx/ppc-xlate.pl

This patch has been tested has passed the selftest.  The patch is also tested with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled.
