Subject: api: add feature invalid check.
X-Git-Tag: submit/tizen/20170927.094753^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8872887249edaecc3fecab972941512e4cb9db4b;p=platform%2Fcore%2Fapi%2Fperipheral-io.git

api: add feature invalid check.

   - add dependency the system info package.
   - almost api return the PERIPHERAL_ERROR_NOT_SUPPORTED
