Subject: [PATCH 03/15] x86/kconfig: Rename x86_64_defconfig to defconfig.x86_64 and i386_defconfig to defconfig.i386

Editing the defconfigs with shell filename completion is unnecessarily
hard due to bad naming: if one remembers 'arch/x86/config/defconfig',
it won't lead to the right files, because the defconfigs are
prefixed with $(ARCH)_.

Under the principle of 'higher order names should go first', prefix
them with 'defconfig' and postfix them with .$(ARCH), and thus make
all x86 configs match the arch/x86/config/defconfig.* pattern.
