hw/ppc/spapr: Convert DIRTY_HPTE() macro as hpte_set_dirty() method

Browse source 
Convert DIRTY_HPTE() macro as hpte_set_dirty() method.

sPAPR data structures including the hash page table are big-endian
regardless of current CPU endian mode, so use the big-endian LD/ST
API to access the hash PTEs.
