PATCH 1/1 ARM: at91: Replace __ASSEMBLY__ with __ASSEMBLER__

While the GCC and Clang compilers already define __ASSEMBLER__ auto- matically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. Let's standardize now on the __ASSEMBLER__ macro to avoid this confusion.

Applied to at91-soc, thanks!
