Jayachandran C. 0dd873372a Cleanup physical address and PTE types on MIPS.
1. Use vm_paddr_t for physical addresses.

There are a few places in the MIPS platform code where vm_offset_t is
used for physical addresses, change these to use vm_paddr_t:
- phys_avail[], physmem_desc[] arrays
- pmap_mapdev(), page_is_managed(), is_cacheable_mem() pmap_map() args
- local variables of various pmap functions

2. Change init_pte_prot() return from int to pt_entry_t, as this can be
64 bit when using 64 bit TLB entries.

3. Update printing of pt_entry_t and of vm_paddr_t to use 'j' format with
uintmax_t. This will be useful later if we plan to use 64bit phsical addr
on 32 bit n32 compilation.
