[PATCH][doc] Document cortex-a17 and cortex-a17.cortex-a7 -m{cpu,tune} options

[Kyrill Tkachov]

Hi all,

As Joseph reminded, new -mcpu options should be documented in 
invoke.texi. This adds the documentation for the cortex-a17 and 
cortex-a17.cortex-a7 values.
Ok to go in if the corresponding support patches posted earlier are 
accepted?

Thanks,
Kyrill
