Heiko Carstens 918c7cad66 s390/fpu: convert __kernel_fpu_begin()/__kernel_fpu_end() to C
Convert the rather large __kernel_fpu_begin()/__kernel_fpu_end() inline
assemblies to C. The C variant is much more readable, and this also allows
to get rid of the non-obvious usage of KERNEL_VXR_* constants within the
inline assemblies. E.g. "tmll %[m],6" correlates with the two bits set in
KERNEL_VXR_LOW. If the corresponding defines would be changed, the inline
assembles would break in a subtle way.

Therefore convert to C, use the proper defines, and allow the compiler to
generate code using the (hopefully) most efficient instructions.
