asm-generic: compat: Support BE for long long args in 32-bit ABIs

32-bit ABIs support passing 64-bit integers by registers via argument
translation. Commit 59c10c52f573 ("riscv: compat: syscall: Add
compat_sys_call_table implementation") implements the compat_arg_u64
macro for efficiently defining little endian compatibility syscalls.

Architectures supporting big endianness may benefit from reciprocal
argument translation, but are welcome also to implement their own.
