Xunlei Pang 978e30c9b4 kexec: move some memembers and definitions within the scope of CONFIG_KEXEC_FILE
Move the stuff currently only used by the kexec file code within
CONFIG_KEXEC_FILE (and CONFIG_KEXEC_VERIFY_SIG).

Also move internal "struct kexec_sha_region" and "struct kexec_buf" into
"kexec_internal.h".
