powerpc/8xx: rework support for 8M pages using contiguous PTE entries
In order to fit better with standard Linux page tables layout, add support
for 8M pages using contiguous PTE entries in a standard page table. Page
tables will then be populated with 1024 similar entries and two PMD
entries will point to that page table.
The PMD entries also get a flag to tell it is addressing an 8M page, this
is required for the HW tablewalk assistance.
