Get rid of register asm statement and use a register pair. This allows the compiler to allocate registers on its own.

You need clang-13 development version which contains commit d058262b1471 ("[SystemZ] Support i128 inline asm operands."). Every older clang version won't be able to complile the kernel for s390 anymore.
This is intended and won't be fixed.
