[PATCH 7/7] bootconfig: Cleanup dummy headers in tools/bootconfig

From: Masami Hiramatsu
Date: Fri Sep 17 2021 - 06:03:31 EST

Cleanup dummy headers in tools/bootconfig/include except
for tools/bootconfig/include/linux/bootconfig.h.
For this change, I uses __KERNEL__ macro to split kernel
header #include and introduce xbc_alloc_mem() and
xbc_free_mem().
