spapr: Remove abuse of rtas_ld() in h_client_architecture_support 

h_client_architecture_support() uses rtas_ld() for general purpose memory
access, despite the fact that it's not an RTAS routine at all and rtas_ld
makes things more awkward.

Clean this up by replacing rtas_ld() calls with appropriate ldXX_phys()
calls.
