[PATCH 2/1, rs6000] make ppc_cpu_supports_hw as effective target keyword [PR108728]

[HAO CHEN GUI via Gcc-patches]

Hi,
  This patch adds ppc_cpu_supports_hw into explicit name checking in
proc is-effective-target-keyword. So ppc_cpu_supports_hw can be used
as a target selector in test directives. It's required by patch2 of
this issue.

Thanks
Gui Haochen
