[PATCH] Revert "ARC: Add guard macro to uapi/asm/unistd.h"

[Vineet Gupta <Vineet.Gupta1@synopsys.com>]

This reverts commit 97bc386fc12deeb41d5bff33548e3002b258d4e0.

Generic syscall table generator relies on ARCH unistd.h as follows:

	void *sys_call_table[NR_syscalls] = {
		[0 ... NR_syscalls-1] = sys_ni_syscall,
	#include <asm/unistd.h>
	};

And turns out that prior dependencies already include that header by
the time preprocessor hits the above. Meaning ARCH unistd.h needs to be
able to included twice.

This however means that perf cross comilation warning will re-appear
which needs to be discussed with perf folks (why they need to include
both libc variant as well as kernel internal header directly).
