I feel we need something like this to avoid the failure of compiling
when build with ARM64_ILP32(which will select COMPAT) and
ARMV8_DEPRECATED (which depends on the opcodes.o).

Subject: [PATCH] arm64: compat: fix wrong dependency of ARMV8_DEPRECATED

When compile with ARM64_ILP32, ARMV8_DEPRECATED will be selected due
to the dependency of COMPAT. It leads to the following error:
    LD      init/built-in.o
    arch/arm64/kernel/built-in.o: In function `cp15barrier_handler':
    /home/bamvor/works/source/kernel/linux_ilp32/arch/arm64/kernel/armv8_deprecated.c:467: undefined reference to `arm_check_condition'
    /home/bamvor/works/source/kernel/linux_ilp32/arch/arm64/kernel/armv8_deprecated.c:467: undefined reference to `arm_check_condition'
    arch/arm64/kernel/built-in.o: In function `swp_handler':
    /home/bamvor/works/source/kernel/linux_ilp32/arch/arm64/kernel/armv8_deprecated.c:386: undefined reference to `arm_check_condition'
    /home/bamvor/works/source/kernel/linux_ilp32/arch/arm64/kernel/armv8_deprecated.c:386: undefined reference to `arm_check_condition'
    Makefile:927: recipe for target 'vmlinux' failed
    make: *** [vmlinux] Error 1

This patch fix this by updating the dependency from COMPAT to
AARCH32_EL0.
