docs: powerpc: syscall64-abi.rst: fix a malformed table
As reported:
Documentation/powerpc/syscall64-abi.rst:53: WARNING: Malformed table.
Text in column margin in table line 2.
=========== ============= ========================================
--- For the sc instruction, differences with the ELF ABI ---
r0 Volatile (System call number.)
This table requires a different notation to be valid.
