Fix malformed table warning in powerpc/syscall64-abi.rst by making
two tables and moving the headings.

Documentation/powerpc/syscall64-abi.rst:53: WARNING: Malformed table.
Text in column margin in table line 2.

r4-r8       Volatile      (Parameters 2-6.)
cr0         Volatile      (cr0.SO is the return error condition.)
