spapr-rtas: fix h_rtas parameters reading

Browse source 
On the real hardware, RTAS is called in real mode and therefore
top 4 bits of the address passed in the call are ignored.
So does the patch.

This converts h_rtas() to use existing rtas_ld() handlers.

This fixed rtas_ld()/rtas_st() to ignore top 4 bits.
