This header file is exported, thus move it to uapi.

Moving the file is correct as far as I can tell, but the extra
#include is not necessary here, as the kernel will automatically
search both arch/arm/include/ and arch/arm/include/uapi/.

The same applies to patches 2 and 4.

Indeed, I'd like to see the include/asm file gone.
