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. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
