arm64: Constify struct kobj_type
'struct kobj_type' is not modified. It is only used in kobject_init()
which takes a 'const struct kobj_type *ktype' parameter.
Constifying this structure moves some data to a read-only section,
so increase over all security.
On a x86_64, compiled with arm defconfig:
Before:
======
text data bss dec hex filename

After:

text data bss dec hex filename
5650 500 352 6502 1966 arch/arm64/kernel/cpuinfo.o
