[PATCH v2] binder: allow ANDROID_BINDER_IPC_32BIT to be unselected on 32bit ARM

[jszhang@marvell.com (Jisheng Zhang)]

As noted in commit d0bdff0db809 ("staging: Fix build issues with new
binder API"), we can add back the choice for 32bit ARM "once a 64bit
__get_user_asm_* implementation is merged." Commit e38361d032f1 ("ARM:
8091/2: add get_user() support for 8 byte types") has added the
support, so it's time to allow ANDROID_BINDER_IPC_32BIT to be
unselected on 32bit ARM so that the 64bit ABI can be tested/used on
32bit systems.

This change allows running the same 32bit userspace build no matter
the kernel is 64bit or 32bit.
