arm64: Add 32-bit sigcontext definition to uapi signcontext.h
The arm64 uapi sigcontext.h can be included by 32-bit userspace modules. Since arm and arm64 sigcontext definition are not compatible, add arm sigcontext definition to arm64 sigcontext.h. Change-Id: I94109b094f6c8376fdaeb2822d7b26d18ddfb2bc Signed-off-by: David Ng <dave@codeaurora.org>
