powerpc: Create DOTSYM to wrap dot symbol usage

Browse Source 
There are a few places we have to use dot symbols with the
current ABI - the syscall table and the kvm hcall table.

Wrap both of these with a new macro called DOTSYM so it will
be easy to transition away from dot symbols in a future ABI.
