[PATCH 2/4] arm64/process: Make loading of 32bit processes depend on aarch32_enabled()

[Andrea della Porta]

Major aspect of Aarch32 emulation is the ability to load 32bit
processes.
That's currently decided (among others) by compat_elf_check_arch().

Make the macro use aarch32_enabled() to decide if Aarch32 compat is
enabled before loading a 32bit process.
