arm64: Add __NR_* definitions for compat syscalls
This patch adds __NR_* definitions to asm/unistd32.h, moves the __NR_compat_* definitions to asm/unistd.h and removes all the explicit unistd32.h includes apart from the one building the compat syscall table. The aim is to have the compat __NR_* definitions available but without colliding with the native syscall definitions (required by lib/compat_audit.c to avoid duplicating the audit header files between native and compat). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
