Newer chips require the PTU_PTE_VALID bit to be set for every page
table entry for context memory and rings.  Additional bits are also
required for page table entries for all rings.  Add a flags field to
bnxt_ring_mem_info struct to specify these additional bits to be used
when setting up the pages tables as needed.
