powerpc/32: Include thread_info.h in head_booke.h
When building with W=1 after commit 80b6093b55e3 ("kbuild: add -Wundef
to KBUILD_CPPFLAGS for W=1 builds"), the following warning occurs.
In file included from arch/powerpc/kvm/bookehv_interrupts.S:26:
arch/powerpc/kvm/../kernel/head_booke.h:20:6: warning: "THREAD_SHIFT" is not defined, evaluates to 0 [-Wundef]
20 | #if (THREAD_SHIFT < 15)
| ^~~~~~~~~~~~
THREAD_SHIFT is defined in thread_info.h but it is not directly included
in head_booke.h, so it is possible for THREAD_SHIFT to be undefined. Add
the include to ensure that THREAD_SHIFT is always defined.
