arm64: guard asm/assembler.h against multiple inclusions
asm/assembler.h lacks the usual guard against multiple inclusion, leading to a compilation failure if it is accidentally included twice. Using the classic #ifndef/#define/#endif construct solves the issue. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
